This practice, purely historical, should no longer be reproduced without supervision from a healthcare professional. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
Decoction — Root
Ancient decoction (abandoned use)
Ancient texts describe a decoction of dried root in water, used in very small quantities.
