This was the only online company I could find to purchase Kai Yeung Pill and is the only thing that eliminates a recurring rash on my shins. I used to buy it locally when I lived in LA, but had no idea how to find it now that I no longer live there. It felt risky to purchase from an unknown company online but I was desperate and it all worked out and now I know where I can get this product going forward. I appreciate you, thank you!
