Dietary supplements
[edit | edit source]Bans
[edit | edit source]Dietary supplements using germander are highly hepatotoxic (causing liver damage). Its sale was prohibited in France by the French Ministry of Health in April 1992. It causes acute hepatitis with an onset delay of 6 weeks to 6 months, and as of 1992 there has been at least one known case of fatal hepatic dysfunction (death from liver damage).[6] As of 2017 its sale has been prohibited in the USA.[7]
History
[edit | edit source]Prior to being identified as hepatotoxic, this herb was sold in European pharmacies and health specialty stores for a variety of uses, including the following:[8]
- slimming diet
- treatment of mild diarrhea
- topical analgesic for oral cavity infections
Cultivation
[edit | edit source]Wall germander can be grown in USDA Zones 5–10. It may be propagated by vegetative cuttings or by the division of established clumps.
