I made a big mistake and ordered their herbal patches. Used for 4 days and had the worst rash/itch in my life. Asked for a refund of remaining product. For 2 months I have been sending requested information over and over with their customer non-support requesting it again with each email. This company is so crooked and carries some of the most useless and dangerous products. My bad for not doing do diligence before buying. Thought I was safe because I use a lot of Chinese herbs without problem. Stir clear
