Info: 60 Veg. Capsules
Butterbur is a shrub in Europe, North America, and Asia that's been used by herbalists for centuries. Modern scientific studies have demonstrated it supports healthy blood flow to the brain and healthy neurological function. Its active constituents, petasines, have been shown to play a role in minimizing the frequency and severity of neurological discomfort such as migraine headaches triggered by bright lights and stress that occasionally occurs in healthy individuals when taken on a prophylactic / preventative basis. It may also help maintain balanced seasonal immune responses. NOW Butterbur is free of harmful levels of Pyrrolizidine Alkaloids (PA's), so is safe to use regularly.

75 mg Butterbur (Petasites hybridus Root) (Standardized to a min. 12% Sesquiterpenes as Petasines)
