I tried to return this product cause of an adverse reaction, my throat was swollen and I had trouble breathing! I tried to email and call IHerb but there is No Contact Information on their website! This company makes it impossible to reach customer service by phone or email ! I wrote to the owner Ray Faraee, located at 17400 Laguna Canyon Rd, Irvine, CA 92618. I never received a response! I am disputing this charge with my credit card company!
