I followed a trail on computor for protein kinase -C and found that Bee Propolis kills this protein that attacks dopamine producing cells. Bee Propolis is not to be taken by people who have any allergic reaction to bees/ pollen /honey etc/ or people with asthma (there are other warnings too) I am not alllergic to bees & went out & bought a bottle of Bee Propolis...so far no noticeable reaction to one capsule a day . Will someone else check this out & see if I came to the right conclusion with what I found??? Thank You
