So far so good
Bought it by recommendation of a chiropractor for the foot pain and the bottom of my foot. After a couple days I've noticed less pain in the bottom of my feet, less burning and tingling

Great to Prevent Mosquito Bites
We live in the southeast and have a lot of mosquitoes. I take this every day and it helps keep me from getting bitten by mosquitoes. I know it sounds weird but it is a trick taught to me by my mother-in-law.

Dr Clark products
All of Dr Clark’s products are super effective, they are so expensive now that it’s getting tougher to buy.
