Wintergreen Oil is more than just a chewing gum flavor. This cleansing, refreshing essence is a key ingredient in some of Cayce's more stimulating massage formulas. When absorbed in small amounts by the skin, Wintergreen oil (Gaultheria procumbens from China) provides soothing relief and increased circulation to bodies under stress. Mild chest clearing properties of Wintergreen Oil add to its effectiveness as a bath water addition, inhalant ingredient and massage formula enhancer. Avoid during pregnancy and with homeopathics.
