Anybody know anything about herbal teas? I'm thinking about buying some bulk herbs to make a tea for liver support and one for digestive support. The liver support blend I'm looking at has burdock root, dandelion root, echinacea, Oregon grape root, yellow dock root, and sarsaparilla. The digestive support blend has fennel, fenugreek, ginger root, and spearmint (it also calls for flax seed but I think flax is bad so I won't use that). Or a different digestive support tea (supposed to be stronger) calls for angelica root, ginger root, yellow dock root, fennel, cinnamon chips, and cardamom pods.
