Safety & Contraindications
Class 2d. Not for long-term use. Do not exceed recommended dose. Sassafras wood contains 1–2% EO, consisting of about 80% of the toxic and hepatocarcinogenic compound safrole; prolonged use is generally discouraged. CAN reports that safrole in the volatile oil is carcinogenic and genotoxic. Because of abortifacient activity of the oil and hepatotoxicity of safrole, its use in pregnancy and lactation is to be avoided. Even safrole-free extracts have reportedly caused tumors. Major symptoms of toxicity include ataxia, depression, and diarrhea, followed by death within 4 hours to 7 days. Rats with safrole in their diet at levels of 0.25% to 1% exhibit biliary proliferation, growth retardation, liver necrosis, primary hepatomas, stomach atrophy, and testicular atrophy. “Sassafras should not be used, internally or externally”. High doses may cause spasm followed by paralysis.
