Dosages (European Pennyroyal) — Should not be taken (APA); 1–4 g herb, or in tea, 3 ×/day
(CAN); 2 tsp (2 g) herb in hot tea (HHB; MAD); 1–4 ml liquid herbal extract (1:1 in 45% ethanol)
3 ×/day (CAN); 0.5–5 ml liquid leaf extract (PNC); 0.6–1.2 ml spirit of pulegium (PNC); 0.05–2
ml EO (I’d hesitate to suggest 0.2 ml, much less 2 ml; I think this is a frequent error in PNC) (PNC)
Contraindications, Interactions, and Side Effects (European Pennyroyal) — Class 2b
Emme-nagogue and uterotonic (AHP) In Canada, allowed in food or beverage only if pulegone-free
(AHP) CAN cautions that pulegone in the volatile oil can be irritant, hepatotoxic, and nephrotoxic
Symptoms following EO ingestion include abdominal pain, agitation, diarrhea, high blood pressure,
lethargy, nausea, pyrexia, and generalized urticaria Abortifacient doses are hepatotoxic and
neph-rotoxic Because of pulegone’s abortifacient activity, its use in pregnancy and lactation is to be
avoided “Both the internal and external use of pennyroyal oil has been contraindicated” (CAN)
Trang 2Death reported following ingestion of 15 ml (ca 1/2 oz) EO, after 2-week consumption of alcoholic extract (with pulegone metabolites in the liver) (AHP) Playing it safe, I like to remind everyone that pregnant women are advised against taking (any medicine) this herb or others because the herbs reportedly have some abortifacient properties Further, pulegone, the active compound, is reportedly absorbed through the skin and may be carcinogenic (I think the warning is overrated but would prefer to err on the side of caution) But many of our generally recommended as safe mints also contain pulegone Delaneyites (a group of adherents of the Delaney Cause, that anything containing a carcinogen is a carcinogen) might outlaw peppermint, one of our best medicinal herbs The Lawrence Review certainly puts pulegone at doubt Pulegone is oxidized by hepatic cytochrome P-450 to the hepatotoxic compound, menthofuran Pulegone or a metabolite is also responsible for neurotoxicity and destruction of bronchiolar epithelial cells It extensively depletes glutathione in the liver Hepatic toxicity from overdoses has been prevented with acetylcysteine administered promptly Rats at 80 to 160 mg/kg/day develop encephalopathies Not to be toyed with Pennyroyal oil is toxic and potentially fatal if ingested Symptoms include abdominal cramps, abdominal pain, nausea, vomiting, rash, dizziness, and alternating lethargy and agitation, leading to kidney failure, massive hepatic necrosis, and disseminated intravascular coagulation Five grams of pennyroyal oil can cause collapse; 11.69 g abortion, collapse, salivation, and unconsciousness Serious toxicity with the tea has not been reported CNS symptoms from ingesting pennyroyal-containing prepa-rations include lethargy, agitation, dizziness, sometimes leading to seizures and auditory and visual hallucinations GI effects include nausea, vomiting, burning in the throat, abdominal pain, and diarrhea (AEH1) EO LD50 = 400 mg/kg orl rat (CAN), LD50 = 4200 mg/kg der rbt (CAN)

not known with proper therapeutic dosages” (PH2) “Side effects that may occur, particularly in
cases of over dosages, include gastroenterosis with vomiting, colic, and diarrhea” (PHR)
“Because efficacy has not been documented, therapeutic use cannot be recommended” (PH2)

Dosages (Evening Primrose) — 250 mg GLA/day (APA); 250 mg oil up to 3 ×/day (APA); 250
mg oil/day/and up (PNC); 270–720 mg EPO equivalent to 1–2 g GLA (obviously an error here)

(StX with 1300 mg EPO with at least 130 mg GLA and 962 mg cis-linoleic acid) 2 ×/day (NH).
Contraindications, Interactions, and Side Effects (Evening Primrose) — Class 1 (AHP) The
literature looks reasonably clean I’ve heard from two separate personal cases of women taking
it satisfactorily for PMS, that it caused migraine-like headaches which they did not experience
before taking EPO Anecdotal but credible As one source of tryptophan, which may convert to
cerebral serotonin, it can alter brain levels of serotonin, which is involved in some migraine
cases Colic, headache, and nausea may occur in a small percentage of subjects CAN reports
patients with schizophrenia on phenothiazines may experience mild dyspepsia and/or increased
risk of epilepsy They rather give it a green light for breastfeeding mothers, since both linoleic
acid and gamma-linolenic acid are normally in breast milk (CAN) The conservative Miller and
Murray (1998) book says, “No adverse effects of EPO have been reported Chronic toxicity and
carcinogenicity studies of EPO in rats, mice, and dogs revealed no important adverse effects or
tumor differences” (MAM) The second edition of the Herbal PDR warns that EPO may possibly
lower the seizure threshold in patients being treated with drugs that lower the seizure threshold
in schizophrenia One of the better sources of gamma-linolenic acid, often known as GLA (and
to some British as gamolenic acid), and tryptophan (FNF) Two large clinical trials with EPO
match clinical relief from cyclical breast pain with bromocriptine and danazol (side effects in
ca 33%) but with virtually no EPO side effects For PMS, Vitex and nutrients (e.g., magnesium
and vitamin B6), are more promising than EPO (DON)
