• Coronary heart disease (CHD). It is unclear if consuming black walnut as part of the diet can reduce the risk for CHD. Details: Epidemiological research has found that people who increase dietary consumption of nuts in general might have a lower risk of CHD and death due to coronary events. However, there is no available evidence showing that eating black walnut, specifically, reduces the risk of CHD (8478,13299). Still, in 2004, the US Food and Drug Administration (FDA) determined that it would allow a qualified health claim stating that consuming 1.5 ounces of walnuts per day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of CHD. The FDA has concluded that this claim is based on supporting, rather than conclusive, evidence (102335).
• Wound healing. Although there is interest in using topical black walnut hull and bark for wound healing, there is insufficient reliable information about the clinical effects of black walnut for this purpose. More evidence is needed to rate the effectiveness of black walnut for these uses.

• Alveolar osteitis. Although there has been interest in using topical clove for alveolar osteitis, there is insufficient reliable information about the clinical effects of clove for this purpose.
• Anal fissures. It is unclear if topical clove oil is beneficial in patients with anal fissures. Details: Preliminary clinical research in patients with chronic anal fissures shows that applying clove oil 1% cream for 6 weeks heals fissures in 60% of patients by the 3-month follow-up, compared with only 12% of patients who used topical lidocaine 5% cream and stool softeners (43487).
• Cough. Although there has been interest in using oral clove for cough, there is insufficient reliable information about the clinical effects of clove for this purpose.
• Dental plaque. Topical clove has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that using a specific toothpaste (Sudantha, Link Natural Products Ltd.) containing a combination of clove, Acacia chundra Willd., malabar nut, bullet wood tree, black pepper, Indian beech, gall oak, Terminalia, and ginger twice daily for 12 weeks can reduce dental plaque, bleeding, and bacteria counts in the mouth when compared with placebo (43570). Other clinical research shows that administration of a mouth rinse containing clove, tea tree oil, and basil 10 mL twice daily for 21 days is as effective as a commercially available mouth rinse containing thymol, eucalyptol, menthol, and methyl salicylate in reducing dental plaque and gum inflammation (92160). It is unclear whether clove, another ingredient, or a combination of these ingredients is responsible for these effects.
• Diarrhea. Although there has been interest in using oral clove for diarrhea, there is insufficient reliable information about the clinical effects of clove for this purpose.
• Dyspepsia. Although there has been interest in using oral clove for dyspepsia, there is insufficient reliable information about the clinical effects of clove for this purpose.

• Gingivitis. Although there has been interest in using topical clove for gingivitis, there is insufficient reliable information about the clinical effects of clove for this purpose.
• Halitosis. Although there has been interest in using oral clove for halitosis, there is insufficient reliable information about the clinical effects of clove for this purpose.
• Hangover. It is unclear if oral clove flower extract is beneficial for reducing hangover severity. Details: Preliminary clinical research in a very small number of healthy males with a history of hangovers shows that taking a clove flower bud polyphenol extract 250 mg prior to drinking brandy (42.8% alcohol) decreases hangover severity scores by around 55% when compared with placebo (100597).
• Hyperhidrosis. It is unclear if topical clove oil is beneficial in patients with hyperhidrosis. Details: Preliminary clinical research in patients with hyperhidrosis of the palms shows that topical application of clove oil 45% in liposome base twice daily for 2 weeks improves hyperhidrosis severity and decreases the rate of sweating by around 34% when compared with a saline control (100596). The validity of these findings is limited by a lack of subject randomization.
• Impaired glucose tolerance (prediabetes). It is unclear if oral clove flower extract is beneficial in patients with prediabetes. Details: Preliminary clinical research in a very small number of patients with prediabetes shows that taking a polyphenolic extract from clove flower buds 250 mg daily for 30 days decreases pre-prandial plasma glucose by 14 mg/dL and postprandial plasma glucose by 40 mg/dL when compared to baseline (100595). The validity of these findings is limited by the very small size of the study and the lack of a control group.
• Mosquito repellent. Small clinical studies suggest that topical clove oil may repel mosquitos for up to 4-5 hours. Details: Preliminary clinical research shows that topical application of undiluted clove oil can repel 100% of mosquitoes for up to 4 hours (43427). Other preliminary research shows that topical application of gel containing clove oil 20% can repel 86% to 97% of mosquitoes for 5 hours (43411).
• Nausea and vomiting. Although there has been interest in using oral clove for nausea and vomiting, there is insufficient reliable information about the clinical effects of clove for this purpose.
• Oral mucositis. Although there has been interest in using topical clove for oral mucositis, there is insufficient reliable information about the clinical effects of clove for this purpose.
• Pain (acute). It is unclear if topical clove is beneficial in patients with acute pain. Details: Preliminary clinical research shows that topical application of a gel containing ground cloves, applied as 4 grams of gel for 5 minutes prior to dental anesthesia injection, can reduce needle stick pain when compared with placebo. The effect of the clove gel on pain seems to be comparable to benzocaine 20% gel (43448).
• Premature ejaculation. Topical clove has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that administration of a multi-ingredient cream preparation (SS Cream) containing clove flower, Panax ginseng root, Angelica root, Cistanches deserticola, Zanthoxyl species, Torlidis seed, Asiasari root, cinnamon bark, and toad venom to the glans penis, one hour prior to intercourse and washed off immediately before intercourse, increases ejaculatory latency time by over 4-fold when compared with placebo in adults with premature ejaculation (2537). It is unclear whether clove, another ingredient, or a combination of these ingredients is responsible for these effects.
• Pruritus. There is limited evidence on the topical use of clove oil in patients with chronic pruritus. Details: Preliminary clinical research in patients with chronic pruritus shows that applying clove oil 10% in petroleum jelly to the skin twice daily for 2 weeks reduces the daily duration of itching by 48 minutes and improves symptom severity and disability scores when compared with placebo (96950). More evidence is needed to rate clove for these uses.

• Dyspepsia. Oral olive leaf extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small study in healthy adults shows that taking a specific combination product containing olive leaf extract 24% and prickly pear cactus 33% (Mucosave, Bionap S.R.L.) 400 mg daily for 8 weeks seems to improve dyspepsia and other gastrointestinal symptoms when compared with placebo (105904). It is unclear if this benefit would occur in patients with clinically diagnosed dyspepsia.
• Exercise-induced respiratory infections. It is unclear if oral olive leaf extract is beneficial for reducing respiratory infections from exercise. Details: A small clinical study in high school athletes shows that taking one tablet of olive leaf extract providing eleuropein 100 mg daily for 2 months during training season does not reduce the incidence of the common cold when compared with placebo. While it may reduce the number of sick days by 28%, a sub-group analysis suggests that this reduction is only evident in female athletes (101860).
• Gastroesophageal reflux disease (GERD). Although there is interest in using oral olive leaf for GERD, there is insufficient reliable information about the clinical effects of olive for this condition.
• Herpes zoster (shingles). Although there is interest in using oral olive leaf for shingles, there is insufficient reliable information about the clinical effects of olive for this condition.
• Influenza. Although there is interest in using oral olive leaf for influenza, there is insufficient reliable information about the clinical effects of olive for this condition.
• Metabolic syndrome. It is unclear if oral olive leaf extract is beneficial for improving body composition and cardiovascular risk factors in patients with metabolic syndrome. Details: A small clinical trial in overweight, middle-aged males at risk for metabolic syndrome shows that taking four capsules of olive leaf extract providing oleuropein 51.1 mg and hydroxytyrosol 9.7 mg daily for 12 weeks improves insulin sensitivity by 15% when compared with placebo. However, body composition, blood pressure, cholesterol levels, and other cardiovascular risk factors were not improved (92245).
• Osteoarthritis. It is unclear if oral olive fruit or leaf extract is beneficial for improving osteoarthritis. Details: Preliminary clinical research shows that taking a freeze-dried aqueous extract of olive fruit 400 mg daily for 8 weeks decreases pain and increases mobility in people with osteoarthritis (14844). Other preliminary clinical research in adults with knee osteoarthritis shows that taking olive leaf extract 50.1 mg daily for 4 weeks improves overall pain measurements by 14%, compared to only 4% in the placebo group. However, many individual measurements of pain are not improved (92252).
• Osteoporosis. It is unclear if oral olive leaf extract is beneficial for osteoporosis. Details: Clinical research shows that taking olive leaf extract (Bonolive, BioActor BV) 250 mg daily for 12 months, along with elemental calcium 400 mg daily, increases osteocalcin levels by about 32% when compared to baseline; this increase was significant when compared to those taking calcium 400 mg plus placebo, who showed a 6% decrease in osteocalcin levels. However, taking olive leaf extract does not significantly increase bone mineral density of the lumbar spine or femur neck when compared with placebo (92247).
• Rheumatoid arthritis (RA). It is unclear if oral olive fruit extract is beneficial for improving RA symptoms. Details: Preliminary clinical research in adults with RA shows that taking an aqueous freeze-dried extract of olive fruit 400 mg daily for 8 weeks does not improve symptoms when compared with control (14844). More evidence is needed to rate the effectiveness of olive for these uses.

• Aging skin. It is unclear if a topical thyme flower and leaf extract reduces wrinkles. Details: A small clinical trial in healthy females aged 40-60 years with wrinkles shows that applying a specific gel preparation (ThymLec 2%, PhytoPharmaTech) containing thyme flower and leaf 1-3% extract in lecithin on the face twice daily for 60 days reduces facial wrinkles when compared with inactive control gel, but not when compared with an active comparator gel containing propanediol, ornithine, phospholipids, and glycolipids (105909).
• Alopecia areata. Topical thyme oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study shows that applying a combination of the essential oils from thyme, rosemary, lavender, and cedarwood improves hair growth in up to 44% of patients after 7 months of treatment when compared with baseline (5177). The validity of this finding is limited by the lack of a comparator group. Additionally, it is unclear if this effect is due to thyme, other ingredients, or the combination.
• Bronchitis. Oral thyme has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some research has evaluated thyme in combination with cowslip. One observational study in adults and children has found that taking a specific product (Bronchipret) containing thyme and cowslip relieves symptoms of bronchitis and increases production of sputum (13557). A clinical study in patients with acute bronchitis shows that taking a similar combination extract (Bronchicum Tropfen) containing thyme and cowslip root 1 mL five times daily for 7-9 days seems to reduce severity and duration of coughing when compared with placebo (49219). Other thyme and cowslip preparations such as Bronchicum Elixir S and Bronchcium Tropfen seem to be similarly beneficial for bronchitis (49223). Thyme has also been studied in combination with other ingredients. A large clinical study in patients with acute bronchitis shows that taking a specific syrup (Bronchipret Saft, Bionorica AG) containing thyme and English ivy leaf 5.4 mL three times daily for 11 days reduces the frequency and duration of cough when compared with placebo (78152). Additionally, an observational study in children with acute bronchitis has found that taking this combination product in an age-specific dosing schema is associated with reduced bronchitis severity and coughing fits when compared to baseline (78181). However, due to the lack of a comparator group, it is unclear if these changes are due to the product or to the natural resolution of the condition.
• Colic. Although there is interest in using oral thyme for colic, there is insufficient reliable information about the clinical effects of thyme for this condition.
• Cough. Oral thyme has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A large open-label, uncontrolled study in adults with acute cough due to an upper respiratory tract infection who purchased a specific syrup (Bronchipret drops, Bionorica AG) containing thyme and English ivy leaf extracts suggests that taking this product as 2.6 mL three times daily for at least 4 days may improve patient-reported bronchitis symptom severity, cough severity, and quality of life, with over 90% of patients reporting overall satisfaction and product tolerability (110401). However, due to the lack of a comparator group, it is unclear if these changes are due to the product or the natural resolution of the condition. Additionally, the validity of these findings is limited by poor study methodology.
• Common cold. Although there is interest in using oral thyme for the common cold, there is insufficient reliable information about the clinical effects of thyme for this condition.
• Dementia. It is unclear if aromatherapy with thyme oil is beneficial in patients with dementia. Details: One very small clinical study in patients with advanced dementia shows that attaching a pad containing thyme oil to the collar area of the shirt does not reduce agitation when compared with lavender oil or unscented grapeseed oil (12213).
• Developmental coordination disorder (DCD). Oral thyme oil has only been evaluated in combination with other oils; its effect when used alone is unclear. Details: One very small clinical study in children with DCD shows that taking thyme oil, in combination with evening primrose oil, fish oil, and vitamin E (Efalex, Efamol Ltd.), seems to modestly improve movement disorders when compared with baseline (5708). The validity of this finding is limited by the lack of a comparator group. Additionally, it is unclear if this effect is due to thyme, other ingredients, or the combination.
• Dyspepsia. Although there is interest in using oral thyme for dyspepsia, there is insufficient reliable information about the clinical effects of thyme for this condition.
• Dysmenorrhea. It is unclear if drinking thyme tea is beneficial for the prevention of dysmenorrhea. Details: One small observational study in adolescents living in Ethiopia has found that drinking thyme tea is associated with a lower occurrence of primary dysmenorrhea when compared with those who did not drink thyme tea (105910).
• Halitosis. It is unclear whether oral thyme is beneficial for halitosis. Details: One small retrospective study in adults with gingival halitosis who received periodontal treatment and oral hygiene instructions suggests that drinking thyme tea twice daily for 1 week is associated with a reduction in volatile sulfur compounds, which is a marker for halitosis, when compared with chlorhexidine or oral hygiene alone (111716). However, the interpretation of this finding is limited by the lack of thyme dosing information and the narrow focus on intraoral halitosis, excluding most extraoral halitosis-associated conditions.
• Laryngitis. Although there is interest in using oral and topical thyme for laryngitis, there is insufficient reliable information about the clinical effects of thyme for this condition.
• Oral mucositis. Although there is interest in using oral and topical thyme for oral mucositis, there is insufficient reliable information about the clinical effects of thyme for this condition.
• Tonsillitis. Although there is interest in using oral and topical thyme for tonsillitis, there is insufficient reliable information about the clinical effects of thyme for this condition. More evidence is needed to rate thyme for these uses.

• IgA nephropathy. It is unclear if oral wormwood is beneficial in patients with IgA nephropathy. Details: Preliminary clinical research in patients with IgA nephropathy shows that taking powdered wormwood (Seda-Leukin, Noor Herbals LLC) 600 mg three times daily for 6 months along with standard treatment reduces proteinuria when compared with baseline. The urinary protein:creatinine ratio decreased from 2340 mg/gram to 315 mg/gram over 6 months. Furthermore, systolic and diastolic blood pressures decreased by 10% and 14%, respectively (93469). The validity of these findings is limited by the lack of a comparator group.
• Insect bite. Although there has been interest in using topical wormwood for insect bites, there is insufficient reliable information about the clinical effects of wormwood for this purpose.
• Osteoarthritis. It is unclear if topical wormwood is beneficial in patients with knee osteoarthritis. Details: Preliminary clinical research in patients with knee osteoarthritis shows that applying an ointment or liniment containing wormwood extract 3% to the knee three times daily for 4 weeks might improve pain, although any pain improvement was not maintained 2 weeks after discontinuation. Topical wormwood appears to be less effective than topical piroxicam gel, which improves pain, stiffness, and physical function when compared with baseline, with benefits maintained 2 weeks after discontinuation (95925). More evidence is needed to rate wormwood for these uses.

Hematologic ...A case of disseminated intravascular coagulation has been reported in a 2-year-old patient after consuming between 5-10 mL of clove oil. The patient was treated with heparin, fresh frozen plasma, protein C, factor VII, and antithrombin III. On the fifth day, the patient started to improve and made a full recovery (43652).

Hepatic ...There are three cases of hepatic failure occurring in children after ingestion of 5-10 mL of clove oil (43395,43419,43652). Liver injury also occurred in a 3-year-old male (96949). These patients were successfully treated with N-acetylcysteine. The course of liver injury seems to be milder and shorter with early N-acetylcysteine treatment (43395,43419,96949). Another patient, who also presented with disseminated intravascular coagulation, was successfully treated with heparin, fresh frozen plasma, protein C, factor VII, and antithrombin III (43652).

Immunologic ...Contact dermatitis and urticaria has been reported following topical exposure to clove oil or eugenol, a constituent of clove oil (12635,43339,43606,43346).

Neurologic/CNS ...CNS depression has been reported in a 7-month-old who was given one teaspoon of clove oil accidentally in place of mineral oil for diarrhea. The patient was successfully treated with supportive care and gastric lavage (43457). A case of confusion and inability to speak has been reported secondary to oral exposure to clove oil and alcohol. The patient required intubation and was successfully treated with thiamine and normal saline (43580). Seizure and coma have been reported in a two-year-old male after ingesting 5-10 mL of clove oil (43652).

Pulmonary/Respiratory ...Clove cigarettes have been associated with throat and chest tightness (43337), pulmonary edema (43618), and fatal aspiration pneumonitis (43599). The causative factor may be clove alone or clove along with other substances found in cigarettes. Clove cigarettes contain significant amounts of nicotine, tar, and carbon monoxide and increase plasma levels of nicotine and exhaled carbon monoxide, which might cause long-term health effects similar to tobacco smoking (12892). According to the American Medical Association, inhaling clove cigarette smoke has been associated with severe lung injury in a few susceptible individuals with prodromal respiratory infection. Also, some individuals with normal respiratory tracts have apparently suffered aspiration pneumonitis as the result of a diminished gag reflex induced by a local anesthetic action of eugenol, which is volatilized into the smoke (43602).
Intravenous injection of clove oil in a 32-year-old female resulted in hypoxia, acute dyspnea, interstitial and alveolar infiltrates, and non-cardiogenic pulmonary edema. The patient was managed with supplemental oxygen and recovered over the next seven days (16384).
Occupational exposure to eugenol, a constituent of clove, has also been reported to cause asthma and rhinitis (43492).

Renal ...Proteinuria and other urinary abnormalities were observed in a seven-month-old infant given one teaspoon of clove oil accidentally in place of mineral oil for diarrhea. The patient was successfully treated with supportive care and gastric lavage (43457).

General ...Orally, olive fruit is well tolerated when used in typical food amounts. Olive leaf extract seems to be well tolerated.
Most Common Adverse Effects:
Orally: Headache and stomach discomfort.

Dermatologic ...Orally, one patient in one clinical trial reported bad skin and acne after using olive leaf extract (101860).

Gastrointestinal ...Orally, three patients in one clinical trial reported stomach ache after using olive leaf extract (101860).

Neurologic/CNS ...Orally, three patients in one clinical trial reported headache after using olive leaf extract (101860).

Psychiatric ...In one case report, a 67-year-old female experienced irritability, anger, a lack of control, and feelings of sadness and negativity after consuming a multi-ingredient product containing olive leaf extract 5 grams, horseradish root, and eyebright daily for 38 days. All psychiatric symptoms disappeared within days of stopping the combined product. It is hypothesized that the hydroxytyrosol component of olive leaf extract contributed to these symptoms due to its chemical similarity to dopamine; however, it is not clear if these symptoms were due to the olive leaf extract or to the other ingredients (96245).

Pulmonary/Respiratory ...Olive tree pollen can cause seasonal respiratory allergy (1543).

General ...Orally, thyme is well tolerated when used in food and seems to be well tolerated when used medicinally. Topically, thyme seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Allergic reactions, diarrhea, dizziness, headache, heartburn, nausea, or vomiting.
Topically: Contact dermatitis and skin irritation.

Dermatologic ...Topically, thyme, thyme oil, or the constituent thymol can cause contact dermatitis and skin irritation (13463,78252,78362,78384,77982,78154,78310,78313,78384). In one study of 100 patients with contact allergies, 5% were attributed to thyme oil as an allergen contained in wound dressings (78362). Toothpastes containing thymol have been associated with cheilitis and glossitis (13463).

Gastrointestinal ...Orally, thyme and thyme oil may cause heartburn, nausea, vomiting, stomach upset, or diarrhea (13557,94033). In a clinical study, two patients using extracts of thyme herb and ivy leaves experienced temporary stomach ache and mild nausea (78181).
Intravaginally, cream containing thyme and garlic has been associated with reports of nausea and vomiting in one clinical study (88387). It is not clear if these adverse effects were associated with thyme, garlic, or the combination.

Genitourinary ...Intravaginally, cream containing thyme and garlic has been associated with reports of vaginal dryness and vaginal irritation in one clinical study (88387). It is not clear if these adverse effects were associated with thyme, garlic, or the combination.

Immunologic ...Orally, thyme can cause allergic reactions; however, this is uncommon (13463). Allergic reactions to thyme might be more common in people who are also allergic to oregano and other Lamiaceae species (3808).

Neurologic/CNS ...Orally, thyme may case headache or dizziness (94033).

Pulmonary/Respiratory ...By inhalation, occupational exposure to thyme dust can cause acute airway obstruction (783,13463,13464,77982,78098).

General ...Wormwood contains thujone, a neurotoxin. When products containing thujone are used orally in medicinal amounts, wormwood may be unsafe.
Most Common Adverse Effects:
Orally: The oil from wormwood leaves can cause diffuse muscle aches, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: The oil from wormwood leaves can cause acute kidney toxicity, rhabdomyolysis, and seizures.

Dermatologic ...Topically, a single case report describes a sensitivity or first degree chemical burn reaction, with facial pain and erythema, after a 50-year-old adult applied a homemade poultice containing wormwood to the face for an unreported length of time (93466).

Gastrointestinal ...Orally, the oil from wormwood leaves can cause nausea and vomiting (662). Use of a home-prepared wormwood extract has been associated with vomiting and severe diarrhea in an infant (93467).

Hematologic ...Orally, use of a home-prepared wormwood extract has been associated with severe metabolic acidosis in an infant (93467).

Immunologic ...Theoretically, wormwood might cause an allergic reaction in people sensitive to the Asteraceae/Compositae family (12815). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.

Musculoskeletal ...Orally, the oil from wormwood leaves can cause diffuse muscle aches and rhabdomyolysis (662).

Neurologic/CNS ...Orally, the oil from wormwood leaves can cause seizures (662).

Renal ...Orally, the oil from wormwood leaves can cause acute kidney toxicity and acute kidney failure (662).

Other ...Chronic ingestion of absinthe, an alcoholic beverage that contains wormwood extract, has been linked to absinthism. Absinthism was first described in the 1800s when absinthe was at its peak levels of consumption. It has been characterized by addiction, gastrointestinal adverse effects, insomnia, auditory and visual hallucinations, tremors, paralysis, epilepsy, and brain damage. There is also increased risk of psychiatric disease and suicide (662,12814,15008). Increasing thujone concentrations of absinthe increases anxiety and decreases attention in healthy individuals (86541). A case of bradyarrhythmias associated with absinthe intoxication has also been reported (86543). However, there is speculation that some of the symptoms of absinthism originally described might be attributed to adulteration with metals or toxic plants such as calamus and tansy, rather than the ingredients usually used in absinthe drinks (15007). Some researchers also suggest that absinthism is not a unique condition and is indistinguishable from alcohol use disorder. In fact, some evidence suggests that the thujone concentrations in the absinthe formulations from the 1800s were too low to cause significant thujone-related toxicities (15008,15009).
