• Dental caries. It is unclear if brushing the teeth with toothpaste containing bamboo salt can prevent dental carries. Details: A small clinical trial in dental students with good oral hygiene and a lack of dental carries shows that brushing with a specific toothpaste containing bamboo salt (Tiger Herb, LG) twice daily for 4 weeks reduces salivary counts of Streptococcus mutans and Lactobacillus when compared to baseline. These reductions were similar to those reported in students using a conventional toothpaste (Crest Complete) (109458). It is unclear whether this toothpaste is effective for preventing dental carries. More evidence is needed to rate bamboo for this use.

• Acne. Although there is interest in using topical eucalyptus for acne, there is insufficient reliable information about the clinical effects of eucalyptus for this condition.
• Asthma. A small clinical study suggests that taking the eucalyptol constituent of eucalyptus orally might have a steroid-sparing effect in some patients with asthma. Details: Preliminary clinical research in patients with steroid-dependent asthma shows that taking eucalyptol, a constituent of eucalyptus oil, 200 mg three times daily orally for 12 weeks, allows for an average reduction in prednisolone doses of 36%, compared with a 7% reduction in those taking placebo (13302).
• Bronchitis. Oral eucalyptol has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some clinical research in patients with chronic bronchitis shows that taking a specific combination product containing eucalyptol and extracts of pine and lime (Myrtol standardized, MYS, Gelomyrtol forte) 900 mg daily orally for at least 1 month decreases the proportion of patients with acute exacerbations by 72%, compared with 53% for those taking placebo (48925). In patients with acute bronchitis, receiving the same product in a dose of 1200 mg daily for 14 days is associated with a reduction in symptoms in all but 1% of patients, compared with 32% of patients receiving placebo (48932).
• Burns. Although there is interest in using topical eucalyptus for burns, there is insufficient reliable information about the clinical effects of eucalyptus for this condition.
• Cancer. Although there is interest in using oral eucalyptus for cancer, there is insufficient reliable information about the clinical effects of eucalyptus for this condition.
• Chronic obstructive pulmonary disease (COPD). A small clinical study suggests that the eucalyptol constituent of eucalyptus might reduce acute exacerbations in patients with stable COPD. Details: Clinical research in adults with stable, moderate to severe COPD shows that adding eucalyptol, 200 mg three times daily, to conventional therapy for 6 months, including the winter season, reduces the proportion of patients experiencing acute exacerbations from 46% to 28% when compared with placebo (104960).
• Cough. Oral eucalyptus oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of four clinical studies in patients with cough associated with bronchitis or upper respiratory tract infection shows that taking eucalyptus oil, either in combination with pine and lime essential oils (Myrtol or Gelomyrtol) or with Origanum syriacum, peppermint, and rosemary essential oils, daily for up to 6 months increases the likelihood of improvement or resolution of cough symptoms by 45% when compared with placebo (110095).
• Dental plaque. Using chewing gum containing eucalyptus extract might reduce dental plaque. Details: Preliminary clinical research shows that chewing gum containing 0.3% to 0.6% eucalyptus extract 3-5 times daily for 4 days to 12 weeks reduces dental plaque when compared with placebo (49010,92863).
• Diabetes. Although there is interest in using oral eucalyptus for diabetes, there is insufficient reliable information about the clinical effects of eucalyptus for this condition.
• Endotracheal intubation-associated adverse effects. It is unclear if nebulized eucalyptus oil is beneficial for prevention of complications associated with endotracheal intubation. Details: A small clinical study in Iranian patients intubated and receiving care in the intensive care unit shows that nebulizing 4 mL of eucalyptus 5% oil in 6 mL of normal saline every 8 hours for 3 days increases oxygen saturation and decreases peak inspiratory pressure, but does not affect the level of consciousness as measured using the Glasgow Coma Scale, when compared with nebulized normal saline (110096).
• Genital herpes. Although there is interest in using topical eucalyptus for genital herpes, there is insufficient reliable information about the clinical effects of eucalyptus for this condition.

• Headache. Topical eucalyptus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that applying a combination of peppermint oil, eucalyptus oil, and ethanol topically to the forehead and temples does not affect headache pain, but improves cognitive performance and produces relaxation, when compared with placebo (3801).
• Influenza. Although there is interest in using oral or inhaled eucalyptus for influenza, there is insufficient reliable information about the clinical effects of eucalyptus for this condition.
• Lice. Topical eucalyptus oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with head lice shows that applying eucalyptus oil 11% and lemon tea tree oil 1% (MOOV Head Lice Solution, Ego Pharmaceuticals Pty Ltd.) reduces the ex-vivo egg hatching rate by only 3%, compared with a 44% reduction with tea tree oil and lavender oil (NeutraLice Natural Lotion), and a 68% reduction with benzyl alcohol, mineral oil, and triethanolamine (NeutraLice Advance) (19188). However, other research in elementary school aged children shows that applying the MOOV Head Lice Solution combination product to the scalp for 10 minutes, once weekly for 3 weeks, is more effective than applying pyrethrins and piperonyl butoxide once weekly for 2 weeks. At 7 days after the last application, 71% of children treated with the eucalyptus formulation were still free of lice, compared with 33% of children in the control group (98492).
• Onychomycosis. Although there is interest in using topical eucalyptus for onychomycosis, there is insufficient reliable information about the clinical effects of eucalyptus for this condition.

• Age-related cognitive decline. It is unclear if oral hops-derived bitter acids are beneficial for memory and attention in patients with age-related cognitive decline. Details: A small exploratory clinical study in older adults aged 45-64 years, with self-awareness of cognitive decline, shows that taking matured hops bitter acids (Kirin Holdings Co. Ltd) 35 mg daily for 12 weeks does not improve memory, attention, or performance on most cognitive tests when compared with placebo (102899). A follow-up clinical study in patients aged 45-69 years with subjective cognitive decline shows that taking the same dose of the same product for 12 weeks also does not improve memory, learning, or selective attention, but might improve divided attention as measured on the Symbol Digit Modalities Test (SDMT), when compared with placebo (105953). Both studies were funded by the supplement manufacturer and conducted in Japan; it is unclear if these findings are generalizable to other geographic locations.
• Anxiety. Although there is interest in using oral hops for anxiety, there is insufficient reliable information about the clinical effects of hops for this condition.
• Attention deficit-hyperactivity disorder (ADHD). Although there is interest in using oral hops for ADHD, there is insufficient reliable information about the clinical effects of hops for this condition.
• Body odor. Although there is interest in using topical hops to reduce body odor, there is insufficient reliable information about the clinical effects of hops for this purpose.
• Insomnia. Taking oral hops extract in combination with valerian root extract seems to be modestly beneficial in patients with insomnia. However, the effect of hops extract when used alone is unclear. Details: In patients with diagnosed sleep disorders, taking hops extract in combination with valerian root for at least 28 days seems to be beneficial. One clinical study in adults with mild insomnia shows that taking two tablets of a combination product containing a total of 83.8 mg hops extract and 374 mg valerian root extract nightly seems to modestly improve subjective sleep measures, including sleep latency, when compared with placebo, after 28 days. However, there was no difference in efficacy between treatment groups after only 14 days (15018). Additionally, a small clinical study in patients with non-organic sleep disorders shows that taking a specific fixed combination product (Ze91019) containing hops extract 120 mg and valerian root extract 500 mg daily for 28 days improves sleep latency when compared with placebo (19413). It is unclear if taking hops and valerian root as a single dose is beneficial in healthy patients. One small clinical study in healthy volunteers with poor sleep shows that taking a specific preparation (Dormeasan, Bioforce AG) containing hops extract 460 mg and valerian root extract 460 mg dissolved in 50 mL of honey water once at night increases total sleep time and time spent in deep sleep when compared with placebo (19418). However, another preliminary clinical study in healthy adults shows that taking a single dose of a specific product (Hova, Zyma S.A.) containing hops extract 200 mg and valerian root extract 400 mg does not improve sleep latency when compared with placebo (6248). Research also shows that taking certain combination products containing hops and at least two other ingredients can improve sleep quality. These combination products have combined hops with lemon balm and valerian (Valerina Natt) (19417); or passionflower and valerian (NSF-3, M/s Tablets India) (88193,89406). However, other combination products have not been beneficial. These have combined hops with soya oil, soya lecithin, and cannabis (Cyclamax, Persee Medica) (55382); or with vitamin B6, zizyphus extract, hydrolyzed milk protein (Lactium), and magnesium oxide (LZ Complex3, Sanofi) (95971).
• Dyspepsia. Although there is interest in using oral hops-derived bitter acids for dyspepsia, there is insufficient reliable information about the clinical effects of hops for this condition.
• Lactation. Although there is interest in using oral hops for increasing lactation, there is insufficient reliable information about the clinical effects of hops for this purpose.
• Menopausal symptoms. It is unclear if oral hops extract is beneficial in patients with menopausal symptoms. Details: Small clinical studies in menopausal patients show that taking a specific hops extract (MenoHop, Biodynamics) 75.1-300 mg standardized to contain 100-200 mcg of 8-prenylnaringenin daily does not improve menopausal symptoms, including hot flashes, after 8-12 weeks of treatment when compared with placebo (55338,55370).
• Overactive bladder. Oral hops extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: An observational study in females with overactive bladder has found that taking a specific combination product (Granu Fink femina, Omega Pharma) containing hops extract 18 mg, sweet sumac bark extract 56 mg, and pumpkin seed oil 227 mg three times daily for 12 weeks decreases the frequency of urination from an average of 0.9 to 0.4 episodes daily and the frequency of leakage when compared with baseline. The study also shows this specific combination product (Granu Fink femina, Omega Pharma) improves quality of life when compared with baseline (103253). The validity of these findings is limited by the lack of a control group. Also, it is unclear if these findings are due to hops extract, other ingredients, or the combination.
• Psychological well-being. It is unclear if drinking non-alcoholic beer containing matured hops bitter acids is beneficial in healthy adults. Details: A clinical study in healthy adults shows that consuming 350 mL of non-alcoholic beer containing matured hops bitter acids 35 mg (Kirin Holdings Co. Ltd) daily for 3 weeks improves mood scores on the Profile of Mood States 2 (POMS2) and Two-dimensional Mood Scale (TDMS) when compared with baseline (107813). The validity of these findings is limited by the lack of a control group.
• Shift work disorder. It is unclear if drinking non-alcoholic beer containing hops is beneficial in patients with shift work disorder. Details: A small open-label clinical study in healthy female nurses working rotating or night shifts shows that drinking 333 mL of non-alcoholic beer containing hops (San Miguel 0% alcohol) at dinner for 2 weeks diminishes sleep latency by about 8 minutes, decreases total activity during the night, and decreases anxiety when compared with baseline. However, it does not appear to increase duration of sleep (55403). The validity of these findings is limited by the lack of a control group and unconfirmed hops content in the beer.
• Vaginal atrophy. Topical hops extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: An open-label, multicenter clinical study in postmenopausal patients with vaginal atrophy shows that inserting 2.5 grams of a vaginal gel containing hops extract 1%, hyaluronic acid, liposomes, and vitamin E (Gynomunal Vaginal gel or Esvegyne, Polichem SA) into the vagina daily for one week followed by twice weekly for 11 weeks reduces vaginal dryness, burning, itching, and rash when compared with baseline (55339). The validity of these findings is limited by the lack of a control group. Also, it is unclear if these effects are due to hops, other ingredients, or the combination.
• Venous leg ulcers. Although there is interest in using topical hops for venous leg ulcers, there is insufficient reliable information about the clinical effects of hops for this condition. More evidence is needed to rate hops for these uses.

• Erectile dysfunction (ED). Preliminary clinical research in middle-aged men with ED shows that taking two capsules of a specific combination product (Revactin, MD Concepts LLC) containing muira puama, ginger root, guarana, and L-citrulline twice daily for 3 months improves scores related to erectile function and intercourse satisfaction, but does not improve sexual desire or orgasmic function scores, when compared to baseline (103224). This study is limited by the lack of a placebo control, the use of per-protocol analysis, and a high dropout rate. In fact, 44% of patients withdrew in order to resume use of phosphodiesterase type 5 (PDE5) inhibitors. Further, it is unclear if these effects are due to muira puama, other ingredients, or the combination.
• Sexual dysfunction. Preliminary clinical research in women with a low sex drive shows that taking 2-6 tablets of a specific combination product (Herbal vX) containing muira puama extract (HV-430) 350-1050 mg and ginkgo extract 32-96 mg modestly improves sexual desire and the frequency of sexual intercourse when compared with baseline (63920). The lack of control group limits the validity of these findings. Further, it is unclear if these effects are due to muira puama, ginkgo, or the combination. More evidence is needed to rate muira puama for these uses.

• Athletic performance. A small clinical trial in healthy men shows that taking sublingual nucleotides 50 mg daily for 14 days increases time to exhaustion during an exercise test by 12 seconds when compared with placebo. There was no effect on heart rate, speed, or perceived exertion (100724). Another small clinical trial in healthy men and women shows that taking 2 capsules twice daily of a supplement (NuBound, Nu Science Laboratories, Inc.) containing nucleotides, amino acids, B vitamins, and prebiotics reduces the time for return to baseline isometric force generation following a resistance exercise protocol by 24 hours when compared with placebo. However, there was no effect on jump peak power (100725). It is not clear if this effect is due to nucleotides, the other ingredients, or the combination.
• Burns. Preliminary clinical research shows that taking RNA and DNA enterally doesn't seem to improve outcomes in burn patients when compared with standard nutritional formulas (5535).
• Irritable bowel syndrome (IBS). A small clinical trial in adults with IBS shows that taking a specific product containing RNA, nucleotides, and other ingredients (IntestAidIB) 500 mg three times daily for 8 weeks modestly improves symptoms of IBS, including abdominal pain, urgency, and incomplete evacuation, when compared with placebo. However, the large effect seen in the placebo group limits the validity of these findings Also, taking this specific product did not improve diarrhea or constipation when compared with placebo (100723). Furthermore, it is not clear if these effects are due to RNA, the other ingredients, or the combination.
• Postoperative infection. Preliminary clinical research shows that administering enteral nutrition supplemented with RNA, eicosapentaenoic acid, and L-arginine during the postoperative period reduces the percentage of patients experiencing postoperative infectious complications and shortens the duration of hospitalization by about 4 days when compared with standard enteral nutrition (5531). It is not clear if this effect is due to RNA, the other ingredients, or the combination. More evidence is needed to rate RNA and DNA for these uses.

• Antidepressant-induced sexual dysfunction. It is unclear if oral yohimbine, a constituent of yohimbe, is beneficial for patients with antidepressant-induced sexual dysfunction. Details: Small clinical trials suggest that taking yohimbine, a constituent of yohimbe, improves sexual dysfunction associated with selective serotonin reuptake inhibitors (SSRIs) (3305,3306,3307,3311,3313,3970,3971,3972,3973). It is unclear if yohimbe bark is beneficial.
• Anxiety. There is limited evidence on the oral use of yohimbine, a constituent of yohimbe, for the management of various phobias. Details: A small clinical study in healthy adults with a fear of flying shows that taking yohimbine hydrochloride 10 mg as an adjunct to virtual reality exposure therapy (VRET) does not improve anxiety measures when compared with VRET alone (86819). However, another small clinical study in healthy adults with claustrophobia shows that taking yohimbine hydrochloride 10.8 mg prior to exposure-based treatment reduces peak fear after one week when compared with exposure-based treatment alone (86794). The effect of yohimbe bark has not been investigated in clinical research.
• Athletic performance. It is unclear if oral yohimbine, a constituent of yohimbe, is beneficial for athletic performance. Details: A small clinical study in professional soccer players shows that taking yohimbine, a constituent of yohimbe, 20 mg daily for 3 weeks does not improve exercise performance or build muscle mass when compared with placebo (86785). However, a small crossover study in physically active females undergoing an anaerobic exercise test shows that taking a single dose of oral yohimbine 2.5 mg 20 minutes prior to repeated sprints increases average power output, total work, and heart rate and decreases average fatigue index when compared with placebo. Additionally, taking yohimbine decreases lactic acid levels and increases epinephrine levels when compared with baseline or placebo (107849). Due to the single-dose nature of this study, the effects of continued administration of yohimbine on athletic performance are unclear. The effects of yohimbe bark have not been investigated in clinical research.
• Depression. It is unclear if oral yohimbine, a constituent of yohimbe, is beneficial in patients with depression. Details: A very small clinical study in patients with treatment-resistant major depressive disorder shows that taking yohimbine, a constituent of yohimbe, 30 mg daily for 10 days along with desipramine does not improve symptoms of depression when compared with desipramine alone (86834). Also, a small crossover trial in patients with major depressive disorder and/or a history of adverse childhood experiences shows that taking yohimbine 10 mg once does not alter approach-avoidance behaviors normally associated with depression when compared with placebo (111402). The effects of yohimbe bark have not been investigated in clinical research.
• Dry mouth. It is unclear if oral yohimbine, a constituent of yohimbe, is beneficial for dry mouth. Details: A very small clinical study shows that taking yohimbine, a constituent of yohimbe bark, 18 mg daily for 5 days improves symptoms of dry mouth in individuals treated with antidepressants when compared with placebo (86886). The effect of yohimbe bark has not been investigated in clinical research.
• Erectile dysfunction (ED). It is unclear if oral yohimbine, a constituent of yohimbe, is beneficial for ED. Details: The effects of yohimbe bark have not been investigated in clinical research. Most small clinical studies suggest that taking yohimbine, a constituent in yohimbe bark, seems to improve symptoms in adults with various types of ED, including organic, psychogenic, mixed, and others (3305,3307,3309,3311,3312,3313,10629,86827,86831,86878)(86882,86888,86896). A meta-analysis in patients with ED shows that taking 5-100 mg of oral yohimbine for 2-10 weeks increases the probability of erectile function improvement when compared with placebo. Also, the use of yohimbine in combination with either L-arginine or trazodone, but not as monotherapy, improves sexual function when compared with placebo (107848). These findings are limited by the high heterogeneity of the included studies. Due to insufficient data, guidelines from the American Urological Association do not recommend yohimbine as a treatment option for ED (86881).
• Fatigue. Although there is interest in using oral yohimbe for fatigue, there is insufficient reliable information about the clinical effects of yohimbe for this purpose.
• Obesity. Although there is interest in using oral yohimbe for obesity, there is insufficient reliable information about the clinical effects of yohimbe for this condition.
• Orthostatic hypotension. It is unclear if oral yohimbine, a constituent of yohimbe, is beneficial in patients with orthostatic hypotension. Details: Some preliminary clinical research shows that taking a single dose of yohimbine 5.4 mg increases systolic blood pressure and standing diastolic blood pressure in patients with orthostatic hypotension when compared with placebo or pyridostigmine (86811,86890). However, other preliminary clinical research shows that taking yohimbine does not improve blood pressure in patients with orthostatic hypotension due to autonomic failure when compared with placebo (86821). The effect of yohimbe bark has not been investigated in clinical research. More evidence is needed to rate yohimbe for these uses.

General ...There is currently a limited amount of information on the adverse effects of bamboo.

Dermatologic ...Topically, bamboo shoots have been reported to cause contact dermatitis in a 44-year-old female (33540).

Gastrointestinal ...In one case report, melanosis coli, pigmentation of the colon wall, was reported following the ingestion of bamboo leaf extract (33547).

Other ...Bamboo shoots are a source of cyanide glycosides. However, the hydrogen cyanide produced by the plant is eliminated during boiling, fermentation, or superheated steam drying of the shoots (96875). During the rescue of a male who jumped into a well which was used for bamboo shoot pickling, cyanide poisoning occurred in 8 individuals. The poisoning caused high anion gap metabolic acidosis in all patients and resulted in two deaths due to cardiac arrest. Some patients also had pulmonary edema and/or infiltration (96874).

General ...Orally, boldo is generally well tolerated when used in amounts commonly found in foods. However, when used in medicinal amounts, boldo can cause significant adverse effects such as hepatotoxicity. There is currently a limited amount of information on the adverse effects of topical boldo; however, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Abdominal pain, nausea, vomiting.
Topically: Dermatitis.
Severe Adverse Effects (Rare):
Orally: Hepatotoxicity, jaundice.

Cardiovascular ...In one report, a 39-year-old obese female developed palpitations and syncope after taking a weight loss supplement containing a combination of boldo, dandelion, and bladderwrack for 3 weeks. The patient was found to have prolonged QT-interval on ECG and frequent episodes of sustained polymorphic ventricular tachycardia (14321). It is not clear whether boldo, another ingredient, or the combination of ingredients is responsible for this adverse effect. The product was not analyzed to determine the presence of any potential toxic contaminants.

Dermatologic ...Topically, boldo can be irritating when applied to the skin (4). In one case report, a healthy 64-year-old patient experienced allergic contact dermatitis in an airborne pattern on the face, arms, and dorsum of both hands following airborne exposure to boldo. After exposure to boldo was avoided, the dermatitis resolved (106433).

Gastrointestinal ...In one case report, a manufacturer of an herbal laxative reformulated their product to contain boldo. Within 5 months of switching to this reformulated product, an 82-year-old male developed abdominal discomfort with gastrointestinal upset including heartburn (13178). In another case, a 72-year-old female reported nausea, vomiting, and anorexia, which were thought to be associated with hepatotoxic effects of a boldo infusion (100304).

Hepatic ...Orally, boldo is thought to potentially cause hepatotoxicity. The volatile oil from the boldo leaf contains the liver toxin, ascaridole. In one case report, a manufacturer of an herbal laxative reformulated their product to contain boldo. Within 5 months of switching to this reformulated product, an 82-year-old male with mild hepatic steatosis and very small gallbladder stones developed elevated liver transaminase levels. Levels normalized following discontinuation of the herbal product (13178). Several other cases of hepatotoxicity have been reported in elderly patients who received infusions of boldo leaves. These patients presented with elevated liver transaminase and bilirubin levels, sometimes up to 200 times the upper limit of normal, as well as nausea, vomiting, anorexia, asthenia, and jaundice. Lab tests and symptoms normalized a few days after stopping boldo (100304,106431).

Immunologic ...Boldo intake has been linked to one case of IgE-mediated anaphylactic allergic reaction (13185).

General ...Orally, diluted eucalyptus oil is generally well tolerated, but the undiluted oil can cause toxicity.
Most Common Adverse Effects:
Orally: Diarrhea, nausea, vomiting.
Topically: Burning, itching, redness, stinging.
Serious Adverse Effects (Rare):
Orally: Signs of toxicity can occur with the undiluted oil at doses as low as 1 mL and include central nervous system depression, shallow respiration, rapid pulse, apnea, coma, and death.
Topically: Prolonged exposure or large amounts of eucalyptus oil can cause agitation, ataxia, drowsiness, muscle weakness, seizures, and slurred speech. The risk of toxicity may be greater in children.
Inhalation (as aromatherapy): Seizures.

Cardiovascular ...Orally, one case of premature ventricular contractions has been reported in a previously healthy 29-year-old male who ingested approximately one ounce of eucalyptus oil (48983).

Dermatologic ...Topically, eucalyptus pollen, leaves, oil, and the constituent eucalyptol can cause contact dermatitis in sensitive people (13303,48931,92856,92858,92859,98497). In some cases, symptoms respond to treatment with topical corticosteroids and tacrolimus (92856). In one case report, transient local redness, burning, and irritation was reported in a 4-year-old child who was bathed in water containing eucalyptus oil. The symptoms resolved within one hour of rinsing the skin with clear water (48983). In a clinical study, treatment with a combination of eucalyptus oil and lemon tea tree oil caused burning, redness, itching, or stinging in up to 20% of the patients. Stinging usually resolved within 10 minutes of application and redness within 30 minutes (19188,98492).

Gastrointestinal ...Orally, eucalyptus oil can cause nausea, vomiting, and diarrhea (48983,48993,48995). Abdominal pain has been reported in a trial of the eucalyptus constituent eucalyptol for inflammatory bowel disease (IBD) (48936).

Immunologic ...A case of IgE-mediated exacerbation of asthma and rhinitis symptoms has been reported in a patient who consumed eucalyptus. Similar worsening of symptoms occurred when the patient inhaled eucalyptus pollen (48957).
Occupational exposure to eucalyptus may cause allergic dermatitis (98497).

Neurologic/CNS ...Orally, eucalyptus oil can cause central nervous system depression, coma, and status epilepticus (12867,48946,48983).
Topically, orally, and by inhalation, eucalyptus oil has been associated with seizures. A systematic review describes the characteristics of 49 children and 61 adults with seizures associated with various routes of administration. Patients with no seizure history were classified as a eucalyptus oil-induced seizure (EOIS), while patients with a history of seizure or susceptibility to seizure were defined as a eucalyptus oil-provoked seizure (EOPS). In EOIS cases, topical use was reported in 74%, inhalation in 22.5%, and ingestion in 3.5%; for EOPS cases, topical use was reported in 79%, inhalation in 16%, and ingestion in 5%. Generalized tonic-clonic seizures are the most prominent type of seizure in EOIS cases (96%). Among EOPS patients, 37% had focal onset motor seizures with impaired awareness, 24% had focal onset aware motor seizures, 13% had focal to bilateral tonic-clonic seizures, and 26% had generalized onset tonic-clonic seizures (107494). One prospective observational study that was included in this systematic review provided additional details on eucalyptus-induced seizures. This study included 18 reports of EOIS and 28 reports of EOPS in adults and children after topical or inhaled use of eucalyptus oil, either alone or in combination with camphor. The time to seizure onset was 0.5-48 hours after topical application, 2-30 minutes after inhalation, and 0.5-6 hours after ingestion. (105028).
One prospective observational study and one case series have described 20 case reports of seizures occurring in children after ingestion of eucalyptus oil. Most of these seizures are generalized tonic-clonic in nature, occur 15-30 minutes after exposure, and do not reoccur following the discontinuation of eucalyptus oil. Seizures have been reported with both overdoses and therapeutic doses (107493,107495) and include cases of both EOIS and EOPS (107495). Additionally, children appear more likely to require intensive care and mechanical ventilation when compared with adult cases (107494).
A case of fever and headache has been reported in a patient who routinely applied a teaspoon of gel containing eucalyptus extract in his throat or nose to treat sore throat or rhinitis (48946).

General ...Orally, hops extract and oil are generally well tolerated when used in food amounts. Hops extract also seems to be well tolerated when used in supplemental amounts.
Most Common Adverse Effects:
Orally: Drowsiness, sedation.

Dermatologic ...Topically, allergic reactions have been reported after contact with the fresh hops plant and plant dust. Contact dermatitis is attributed to the pollen (4,12,105930).

Genitourinary ...Orally, supplements containing hops and soy have been associated with 4 cases of postmenopausal bleeding (55404). It is unclear if this effect is due to hops, soy, or the combination. Also, menstrual disturbances have been reported in female workers harvesting hops (10684,55405).

Neurologic/CNS ...Orally, hops might cause drowsiness and sedation. Historically, hops are thought to have sedative effects, since workers harvesting hops were observed to tire easily after oral contact with hop resin. The European Medicines Agency states that hops may have sedative effects; however, there is a lack of clinical research confirming that hops extract causes drowsiness and sedation (105930).

Pulmonary/Respiratory ...Occupational exposure to dust from hops, usually in combination with dust from other products, is associated with chronic respiratory symptoms such as dry cough, dyspnea, chronic bronchitis, and other occupational respiratory diseases (55333,55414).

Genitourinary ...Orally, yohimbine may cause dartos contraction or decreased libido in some patients (86786,86882). A case of severe intractable priapism has been reported for a 42-year-old male who took a supplement containing yohimbe extract the previous day for sexual enhancement. Treatment with phenylephrine 400 mcg was unsuccessful at resolving the priapism, so surgical insertion of a proximal cavernosal spongiosum shunt was needed (86804).

Hematologic ...A case of drug-induced agranulocytosis has been reported following prolonged use of oral yohimbine, a constituent of yohimbe (86877).

Immunologic ...There is one report of a hypersensitivity reaction including fever; chills; malaise; itchy, scaly skin; progressive renal failure; and lupus-like syndrome associated with ingestion of a one-day dose of yohimbine, a constituent of yohimbe (6169).

Musculoskeletal ...Orally, yohimbine, a constituent of yohimbe, may cause muscle aches (86850).

Neurologic/CNS ...Orally, yohimbine, a constituent of yohimbe, has been associated with reports of general central nervous system (CNS) and autonomic excitation, tremulousness, head twitching, seizure threshold changes, enhanced brain norepinephrine release, decreased energy, dizziness, vertigo, and headache (3312,3971,86774,86779,86786,86804,86827,86857,86870,86882)(86883). Cold feet and chills have also been reported with yohimbine (86827,86896). Other adverse reactions include flushing and diaphoresis (17465). Excessive doses of yohimbine can also cause paralysis (11,18). A case of acute neurotoxicity characterized by malaise, vomiting, loss of consciousness, and seizures has been reported for a 37-year-old bodybuilder who ingested a single dose of yohimbine 5 grams. Improvement was seen within 12 hours following treatment with furosemide, labetalol, clonidine, urapidil, and gastrointestinal decontamination (86801).

Psychiatric ...Orally, yohimbine, a constituent of yohimbe, may increase malaise, fatigue, insomnia, restlessness, agitation, and anxiety (3312,3970,3971,17465,86786,86801,86804,86822,86827,86834)(86868,86878,86882,86896). In a clinical study of healthy subjects, administration of yohimbine increased impulsivity, with larger doses increasing impulsivity more than 50% (86784,86810).

Pulmonary/Respiratory ...Orally, yohimbine, a constituent of yohimbe, may cause bronchospasm, tachypnea, cough, and rhinorrhea (17465,86825,86850). A case of sinusitis characterized by pain and discomfort above both eyes has been reported for a 59-year-old male taking yohimbine 5.4 mg three times daily to treat erectile dysfunction. Symptoms resolved within 24 hours of discontinuing yohimbine. The effect was attributed to the alpha-2 adrenergic antagonist effects of yohimbine (94112).
