A lot of stores sell Flor-Essence and the whole line of Flora line of products. If it's not in a health store in your town try online suppliers. Essiac is available in its original design bottle too. If it has Rene Caisse's signature on the bottle, it's authentic Essiac. You have to boil it for 10 minutes then let stand covered for 10-12 hours. A bit of a bother, but its also available mixed. Have to keep in fridge and take a 1/4 cup a day in tea or warm water. Do not microwave or nutrients will be destroyed by radiation.
I take Primadophilus Optima 35 billion per enteric coated capsule. 1 a day at supper.
