Safety & Contraindications
Class 1. None reported. None known. But Gruenwald mentions rare GI complaints, and even rarer contact allergies. He adds that long-term administration may occasionally cause cardiac disorders, headache, mydriasis, restless states, and sleeplessness, the latter two the main indications, now side effects of prolonged use. Full-body valerian baths should be monitored in cases of dermatosis, major skin injuries, cardiac insufficiency, or hypertonia. No contraindications, adverse effects, or interactions except for the effect of the tincture on driving ability. Ironically, “There is some concern about continual use, which may cause minor side effects, including headaches, excitability, and insomnia”. AHP minimizes published concern about toxicity of valepotriates, due to poor absorption and quick degradation into less toxic metabolites. If we accept this, we have to minimize medicinal potential of the valepotriates as well. CAN says, “There have been no reported side effects to valerian. The oil is unlikely to present any hazard in aromatherapy”. After all those kind words CAN says, “The safety of valerian during pregnancy and lactation has not been established and should, therefore, be avoided.” CNS depressant activity may potentiate pharmaceutical sedatives. For some 5% of people, valerian may be slightly stimulating.
