I've been using their Kidney 6 Tea, Lymphatic Tea and some tinctures and have notice a huge difference in my legs. The swelling has decreased and varicose veins don't hurt with the high humidity of summer! I always believed in herbal teas/Chinese medicine for healing but it's so expensive to buy and mix the blends yourself (plus you have to know what you're doing). I love how easy it is for me to buy all the herbs already designed exactly for my problem!
