Daily Dose

Untitled Document

“The amount of plant material required to obtain a lethal dose is quite small: The LD50 in dogs is about 2.3 g of leaves/kg, or about 11.5 mg/kg of taxine alkaloids. So a dog could consume a potentially lethal dose while playing with Taxus species branches or sticks.”
