General
...Orally, lavender is well tolerated in food amounts and seems to be well tolerated in larger amounts.
Topically, lavender oil seems to be well tolerated.
Most Common Adverse Effects:
Orally: Breath odor, constipation, diarrhea, dyspepsia, eructation, headache, and nausea.
Topically: Allergic contact dermatitis (with lavender oil).
Serious Adverse Effects (Rare):
Topically: Cases of gynecomastia have been reported in prepubertal males using lavender oil.
Cardiovascular ...Orally, a specific lavender oil ingredient (Silexan) has been associated with palpitations (103061).
Endocrine ...Topical products containing lavender oil alone, including a product referred to as agua de violetas, or in combination with tea tree oil have been linked to at least six cases of gynecomastia when used in prepubertal males. In each case, gynecomastia resolved when the lavender oil products were discontinued. It is thought that the estrogenic and antiandrogenic activity of lavender oil and tea tree oil resulted in gynecomastia in these cases (15254,95643).
Gastrointestinal ...Orally, lavender oil, including a specific lavender oil ingredient KG), may cause gastrointestinal disturbance, including dyspepsia, diarrhea, breath odor, eructation, and nausea (58077,58080,58098,93004,103061). Tincture of lavender has been linked to cases of constipation and increased appetite; however, it is unknown if this occurred at a greater rate than with placebo (9792).
Immunologic ...Topically, use of lavender oil, such as in personal care products, might cause allergic contact dermatitis in some patients (6,101728). There have been numerous case reports of allergic contact dermatitis and eczema linked to lavender oil exposure from shampoos, lotions, fragrances, or direct application of oil to pillows (10031,58043,58109,58120,101728).
Neurologic/CNS ...Orally, lavender flower powder, tincture of lavender containing 50% alcohol, and a specific lavender oil ingredient (Silexan) have been linked to headache (9792,103061,109860). Headache has also been reported rarely following lavender oil aromatherapy (109860).
Pulmonary/Respiratory ...In one case report, a 34-year-old Japanese female presented with complaints of dyspnea, cough, and fever 2 weeks after initiating lavender essential oil therapy via humidifier. The patient had an oxygen saturation of 88% and was diagnosed with acute eosinophilic pneumonia. Symptoms improved after a course of corticosteroids and discontinuation of aromatherapy (109979).
General
...Orally, neem extracts seem to be well tolerated in adults.
However, high-quality assessment of safety has not been conducted. In children, oral use of neem oil can cause serious adverse effects. Topically, neem seems to be well tolerated in children and adults.
Most Common Adverse Effects:
Topically: Contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Cardiac arrest, nephrotoxicity, and ventricular fibrillation with neem leaf in adults. Encephalopathy, hematologic abnormalities, hepatotoxicity, and nephrotoxicity with neem oil in infants and young children.
Cardiovascular ...Orally, neem leaf has been reported to cause ventricular fibrillation and cardiac arrest after ingestion in humans (64873,64870).
Dental ...Topically, use of neem twigs to brush teeth, which is a traditional dental hygiene practice in India, has been associated with vitiligo of the lips. The limonoid constituents in neem, which have been shown to inhibit melanogenesis and have cytotoxic effects, combined with repeated, local trauma from this dental hygiene practice are thought to cause this leucodermic reaction. In a case series of seven patients experiencing vitiligo of the lips from neem twigs, use of toothpaste and topical tacrolimus along with avoidance of neem stopped the progression of depigmentation in all patients. Repigmentation was reported in four of the seven patients 12 months after discontinuing neem-based dental hygiene practices (100958).
Dermatologic ...Topically, neem products have been associated with dermatologic reactions. Some case reports have associated the use of topical neem oil with contact dermatitis (64851,94568,102867). In one case series, the topical application of neem seed extract shampoo was associated with skin irritation, red spots, and a burning feeling of the scalp (64848). Use of neem twigs to brush teeth, which is a traditional dental hygiene practice in India, has been associated with vitiligo of the lips. The limonoid constituents in neem, which have been shown to inhibit melanogenesis and have cytotoxic effects, combined with repeated, local trauma from this dental hygiene practice are thought to cause this leucodermic reaction. In a case series of seven patients experiencing vitiligo of the lips from neem twigs, use of toothpaste and topical tacrolimus along with avoidance of neem stopped the progression of depigmentation in all patients. Repigmentation was reported in four of the seven patients 12 months after discontinuing neem-based dental hygiene practices (100958).
Gastrointestinal ...Orally, neem oil has been reported to cause vomiting and loose stools in infants and small children (3473,3474,3476,64865).
Genitourinary ...Orally, neem leaf has been reported to cause oliguria and anuria in adults (12833,12834). After a single intrauterine instillation, purified neem oil has been reported to cause endometritis in healthy, tubectomised females (64886).
Hematologic
...Orally, neem leaf has been reported to cause hemolysis in adults (12835).
In one case report, a 35-year-old male with diabetes and glucose-6-phosphate dehydrogenase (G6PD) deficiency developed hemolytic anemia and jaundice after drinking several liters of neem tea daily for 3 weeks. All symptoms resolved after discontinuation and supportive treatment (94571). Orally, neem oil has been reported to cause metabolic acidosis, anemia, and polymorphonuclear leukocytosis in infants and young children (3473,3474,3476,64865).
A single intrauterine instillation of purified neem oil has been reported to cause mild transient eosinophilia in healthy, tubectomised females (64886).
Hepatic ...Orally, neem oil has been associated with reports of hepatotoxicity in infants and children. These adverse effects occurred after single doses of neem oil ranging from a few drops to 60 mL. Pathologic findings on liver biopsy reports have been consistent with Reye-like syndrome (3473,3474,3475).
Immunologic ...Topically, a case of aggravated bullous pemphigoid requiring hospitalization is reported in a 47-year-old patient with this autoimmune condition after application of neem oil to blisters for an unknown duration (111715).
Neurologic/CNS ...Orally, single doses of neem oil ranging from a few drops to 60 mL have been associated with reports of encephalopathy in infants and small children. Symptoms include drowsiness, seizure, loss of consciousness, coma, cerebral edema, Reye-like syndrome, and death within hours of ingestion (3473,3474,3476,3476,64855,94750). There is also at least one case report of neurotoxicity in an adult after ingestion of a neem-based pesticide. A 35-year-old female experienced neurotoxicity requiring intensive medical care and ventilation after ingestion of a pesticide containing azadirachtin, a constituent of neem oil (64858).
Ocular/Otic ...In one case report, a 35-year-old female developed toxic optic neuropathy and vision loss in both eyes lasting for two days after consuming 150 mL of neem oil in a suicide attempt five days earlier (64856).
Renal ...Orally, neem leaf has been reported to cause oliguria, anuria, acute tubular necrosis, and nephrotoxicity in adults (12833,12834). There are some case reports of children developing Reye-like syndrome after ingestion of neem oil. Pathologic findings on renal biopsy reports have been consistent with Reye syndrome (3473,3474,3475).
General ...Orally, rosemary seems to be well tolerated when used in appropriate medicinal amounts. Undiluted rosemary oil or very large quantities of rosemary leaf should not be consumed. Topically and as aromatherapy, rosemary seems to be well tolerated.
Dermatologic ...Topically, rosemary use can lead to photosensitivity, erythema, dermatitis, and cheilitis in hypersensitive individuals (4,6).
Immunologic
...Topically, allergic reactions can occur.
When used in the mouth, lip and gum edema have occurred (101173). When used on the skin, allergic contact dermatitis has occurred, likely due to the constituent carnosol (71715,71924,71926).
Rosemary might also cause occupational asthma. A case of occupational asthma caused by several aromatic herbs including thyme, rosemary, bay leaf, and garlic has been reported. The diagnosis was confirmed by inhalation challenges. Although all of the herbs caused immediate skin reactivity, a radioallergosorbent test (RAST) showed that garlic was the most potent allergen by weight, with rosemary and the other herbs showing less reactivity (783).
Neurologic/CNS ...Orally, the undiluted oil, as well as the camphor constituent of rosemary, might cause seizures (4,5,6,12868).
