• 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.
• Flatulence. Although there has been interest in using oral clove for flatulence, 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.

• Biliary disorders. Although there has been interest in using oral wormwood for biliary disorders, there is insufficient reliable information about the clinical effects of wormwood for this purpose.
• Crohn disease. Small clinical studies suggest that oral wormwood may modestly improve symptoms in patients with Crohn disease. Details: Preliminary clinical research in patients with Crohn disease shows that taking a specific product (SedaCrohn, Noor Herbals, LLC) containing powdered wormwood 750 mg 2-3 times daily for 6-10 weeks improves quality of life and mood, increases symptom remission, and reduces corticosteroid requirements when compared with placebo (86545,93468). Clinical remission occurred in 8 out of 10 patients taking wormwood, compared with only 2 out of 10 patients taking placebo (93468).
• Depression. Although there has been interest in using oral wormwood for depression, there is insufficient reliable information about the clinical effects of wormwood for this purpose.
• Dyspepsia. Although there has been interest in using oral wormwood for dyspepsia, there is insufficient reliable information about the clinical effects of wormwood for this purpose.
• Gastritis. Although there has been interest in using oral wormwood for gastritis, there is insufficient reliable information about the clinical effects of wormwood for this purpose.
• 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.

• Atopic dermatitis (eczema). Although there is interest in using topical yarrow for atopic dermatitis, there is insufficient reliable information about the clinical effects of yarrow for this condition.
• Dysmenorrhea. It is unclear of oral yarrow tea is beneficial for improving symptoms of dysmenorrhea. Details: Preliminary clinical research in patients with moderate to severe dysmenorrhea shows that drinking a tea made with yarrow 4 grams three times daily for the first three days of two menstrual cycles modestly reduces dysmenorrhea pain when compared with a placebo tea (105361).
• Gingivitis. A mouthwash containing yarrow has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that using a mouthwash containing a combination of yarrow, juniper, and stinging nettle for 3 months does not improve dental plaque or gingivitis in patients with gingival inflammation when compared with a control group (76443).
• Irritable bowel syndrome (IBS). Oral yarrow has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with mild to moderate IBS shows that taking a capsule containing yarrow, ginger, and Boswellia serrata three times daily for 30 days improves pain by 46% and gastrointestinal symptoms by 60% when compared with placebo. Patients also experienced an improvement in overall mood when compared with placebo (96673). It is not clear if these effects are due to yarrow, the other ingredients, or the combination.
• Multiple sclerosis (MS). It is unclear if oral yarrow is beneficial for patients with MS. Details: A small clinical study in adults with relapsing-remitting MS shows that taking yarrow whole plant extract 250 mg or 500 mg daily in conjunction with conventional treatments for 12 months reduces the annual relapse rate and increases time to first relapse when compared with placebo. Taking yarrow 500 mg daily also reduced disability scores and improved functional scores when compared with either yarrow 250 mg daily or placebo (100346). However, most of the patients enrolled in the study were under 40 years of age, with undefined disease severity.
• Nipple fissures. It is unclear if topical yarrow is beneficial for patients with nipple fissures. Details: Preliminary clinical research in patients with inflamed nipples and/or nipple fissures shows that topical application with yarrow twice daily after breastfeeding for 7 days reduces redness and pain when compared with baseline. Yarrow 30 grams was boiled in 1 liter of water for 10 minutes. The benefits seen with yarrow were not significantly different from topical mountain honey or breast milk, both of which were also beneficial when compared with baseline (105359).
• Oral mucositis. It is unclear if gargling with yarrow is beneficial for oral mucositis. Details: Preliminary clinical research in patients with chemotherapy-induced oral mucositis shows that gargling with 15 mL of a routine solution containing yarrow distillate 50%, 4 times daily for 14 days, reduces symptom severity by 87%, compared with a worsening in severity in those using the routine solution alone. Of those using yarrow, all patients were able to eat solid foods at 14 days compared with about 40% of those using routine treatment alone. About 3.75 grams of yarrow flower was needed for each 7.5 mL of distillate and the solution was held for 3 minutes in the mouth before gargling (106664). It is unclear if the patients were adequately blinded, as the taste of the two solutions may have differed.
• Tonsillitis. Oral yarrow has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in children 6-18 years of age with acute non-bacterial tonsillitis shows that taking a specific combination product (Imupret, Bionorica AG) containing yarrow and six other herbal ingredients along with standard care reduces the severity of tonsillitis symptoms when compared with standard care alone. Additionally, taking this combination product improved physician- and patient-rated assessments of general condition when compared with standard care alone (100347). It is not clear if these effects are due to yarrow, other ingredients, or the combination.
• Vaginal candidiasis. It is unclear if intravaginal yarrow is beneficial for vaginal candidiasis. Details: Clinical research in patients with vulvovaginal candidiasis shows that intravaginal application of 5 grams of a cream containing yarrow extract 2% for 7 days modestly reduces Candida growth and improves vulvar erythema and other general symptoms when compared with baseline. However, the cream was less effective overall than vaginal clotrimazole 1% cream (105360).
• Wound healing. It is unclear if topical yarrow is beneficial for wound healing. Details: Clinical research in postpartum adults who have had an episiotomy shows that applying approximately 1 cm of an ointment containing yarrow 5% over the clean and dried suture area twice daily for ten days reduces perineal pain, redness, and edema 1-2 weeks after the procedure when compared with placebo ointment or no treatment. However, using the yarrow ointment did not affect discharge time or reduce the occurrence of dehiscence (96910). More evidence is needed to rate yarrow for these uses.

General ...Orally, black walnut fruit (nut) is well tolerated. However, the leaf, bark, and hull of black walnut contain high quantities of tannins, which may cause adverse effects when used orally or topically.
Most Common Adverse Effects:
Orally: The leaf, bark, and hull can cause gastrointestinal upset.
Topically: Hull preparations may cause a temporary yellow or brown discoloration at the site of application. The leaf, bark, and hull can cause skin irritation.
Serious Adverse Effects (Rare):
Orally: The bark may increase the risk for tongue cancer or lip leukoplakia when used long-term.
All routes of administration: Allergic reactions, including anaphylaxis.

Dermatologic ...Topically, black walnut leaf, bark, or hull may have an irritating effect on the skin due to tannin content. Black walnut hull preparations might cause a temporary yellow or brown discoloration of the skin at the site of application (12).

Gastrointestinal ...Orally, black walnut leaf, bark, or hull may cause gastrointestinal upset due to tannin content (12). Also, daily use of the juglone-containing bark of a related species (English walnut) is associated with increased risk of tongue cancer and lip leukoplakia (2,12).

Hepatic ...Orally, black walnut leaf, bark, or hull may cause liver damage if taken for extended periods of time due to tannin content (12).

Immunologic ...Tree nuts, which include black walnuts, can cause allergic reactions in sensitive individuals. Due to the prevalence of this allergy in the general population, tree nuts are classified as a major food allergen in the United States (105410).

Renal ...Orally, black walnut leaf, bark, or hull may cause kidney damage if taken for extended periods of time due to tannin content (12).

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 ...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).
