Thank you for the information. Real natural cures is a learning process. I will add this to my first aid list and try ot out on various ailments. Ever since I heard about HCQ, I found out that it was derived from Quinine. I have been taking it ever since. No side effects, I don't really know of it is a positive, but there has been no negatives. In conjunction with zinc, it inhibits viral replication, just like Ivermectin and many of the other Anthelminics (anti-parasitics).
