• Asthma. Oral anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with allergic asthma shows that drinking one cup of tea prepared with multiple ingredients, including anise, twice daily for 6 months reduces sleep discomfort, cough frequency, and cough intensity when compared with placebo (19056). It is unclear if these findings are due to anise, other ingredients, or the combination.
• Constipation. Oral anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A very small crossover trial in patients with constipation shows that taking an herbal tea containing a combination of anise, fennel, elderberry, and senna daily for 5 days can decrease colon transit time, increase the number of daily evacuations, and improve the perception of bowel function when compared with placebo (49494). It is unclear if these findings are due to anise, other ingredients, or the combination.
• Depression. It is unclear if oral anise oil is beneficial in patients with depression. Details: A small clinical study in adults with mild to moderate depression and irritable bowel syndrome (IBS) shows that taking enteric-coated anise oil 200 mg three times daily for 4 weeks improves symptoms of depression by an additional 28% when compared with placebo and an additional 32% when compared with peppermint (94947).
• Diabetes. It is unclear if oral anise seed powder is beneficial in patients with diabetes. Details: A small clinical study in adults with type 2 diabetes shows that taking anise seed powder 5 grams daily for 60 days decreases fasting blood glucose levels by 36%, total cholesterol levels by 7.5%, and triglyceride levels by 15% when compared to baseline. Fasting blood glucose significantly increased in the control group, and total cholesterol and triglyceride levels were relatively unchanged (94953).
• Dysmenorrhea. Although there has been interest in using oral anise for dysmenorrhea, there is insufficient reliable information about the clinical effects of anise for this purpose.
• Dyspepsia. It is unclear if oral anise powder is beneficial in patients with dyspepsia. Details: A small clinical study in adults with postprandial distress syndrome shows that taking anise powder 3 grams three times daily for 4 weeks improves quality of life and symptoms of functional dyspepsia when compared with placebo. Of the evaluated symptoms, improvement was seen in all categories when compared to placebo except for nausea and vomiting, which were present in less than 5% of patients at baseline (94944,94945).
• Irritable bowel syndrome (IBS). It is unclear if oral anise oil is beneficial inpatients with IBS. Details: A small clinical study in adults with IBS shows that taking enteric-coated anise oil 200 mg three times daily for 4 weeks eliminates IBS symptoms in 75% of patients, compared with 53% of patients taking peppermint oil and 35% taking placebo. The greatest symptom improvement occurred with abdominal pain, bloating, and reflux, and was maintained for an additional 2 weeks after treatment completion (94946).
• Lactation. It is unclear if oral anise tea is beneficial for increasing human milk production. Details: A moderate-sized clinical study in post-partum adults shows that drinking a tea containing anise 2 grams and black tea 1 gram 3 times daily with meals for 7 days increases the volume of pumped human milk on day 7 by an average of 98 mL and 113 mL, respectively, when compared with a placebo of black tea 3 grams daily and when compared with a control group not assigned to any tea or galactagogues (112863).
• Lice. Topical anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in children 6-14 years of age shows that application of a topical spray containing anise oil, coconut oil, and ylang ylang oil three times at 5-day intervals is 92% effective for the treatment of head lice and seems to be comparable in effectiveness to a spray containing permethrin, malathion, piperonyl butoxide, and isododecane (13483).
• Menopausal symptoms. It is unclear if oral anise seed extract is beneficial in patients with menopausal symptoms. Details: A small clinical study in postmenopausal adults shows that taking anise seed extract 330 mg three times daily for 4 weeks reduces the frequency and severity of hot flashes by approximately 75% when compared with placebo (94948).
• Migraine headache. It is unclear if topical anise essential oil is beneficial in patients with migraine headache. Details: A small clinical study in adults with migraine headache shows that applying 2 mL of a cream containing anise essential oil 7% to the temporal and forehead zones at the onset of a migraine reduces the impact of the headache by approximately 10% when compared with a control cream. However, there was no effect of the anise cream on analgesic use or average headache severity when compared with placebo cream. Additionally, due to the strong smell of the anise cream, patient blinding may have been compromised (100166).
• Premenstrual syndrome (PMS). It is unclear if oral anise extract is beneficial in patients with PMS. Details: A small clinical study in female college students with PMS shows that taking anise extract 110 mg three times daily, starting 7 days before menstruation and ending 3 days after, improves concentration, mood, irritability, sleep, food cravings, and other symptoms of PMS, as measured using the Premenstrual Symptoms Screening Tool, when compared with placebo (103875). More evidence is needed to rate anise 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.

• 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.

General ...Orally, clove is well tolerated when consumed as a spice; however, clove oil in doses of only 5-10 mL can be toxic in children. Topically, clove is generally well tolerated. When inhaled or used intravenously, clove may be unsafe.
Most Common Adverse Effects:
Topically: Burning, contact dermatitis, dental decay, itching, mucous membrane irritation, tingling, ulcers.
Inhaled: Dental decay, hypertension, itching, tachycardia.
Serious Adverse Effects (Rare):
Orally: Liver failure, respiratory distress.
Inhaled: Pneumonitis, pulmonary edema, respiratory distress.

Cardiovascular ...Smoking clove cigarettes increases heart rate and systolic blood pressure (12892).

Dental ...Population research has found that the risk of dental decay is increased in clove cigarette smokers (43332). Repeated topical application of clove in the mouth can cause gingival damage and skin and mucous membrane irritation (4,272,512). Eugenol, a constituent of clove and a material commonly found in dentistry, has been associated with side effects including gum inflammation and irritation (43365,43373,43522).

Dermatologic ...The American Dental Association has accepted clove for professional use, but not nonprescription use, due to potential damage to soft tissue that may be induced by clove application. In clinical research, small aphthous-like ulcers appeared in the area of the mouth where clove gel was applied in four participants (43448). Skin irritation and stinging have been reported with clove oil application (43338,43626). In a 24-year-old, exposure to a clove oil spill resulted in permanent local anesthesia and anhidrosis, or lack of sweating, at the affected area (43626).

Endocrine ...A case of hypoglycemia and metabolic acidosis have been reported after administration of one teaspoon of clove oil to a seven-month-old infant (43457). A case of electrolyte imbalance following accidental ingestion by a seven-month-old has also been reported (6).

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).
