Caisse-ACT (was called Essiac [TM] [now under trademark]) (ACT – Alcohol-free Concentrated Tincture). Herbactive has made this extract for over 30 years (before it was put under trademark), when the formula was available to all who wanted to make use of it. So we have made the decoction using the original formula. We concentrated the extract so that it was easier to dispense and take as a medicine, preserving it in food-grade glycerin (alcohol-free). It is naturally thick.
