There are many echinacea formulas [echinacea alone or in combinations]on the market.

There are also echinacea formulas [tinctures] of less good quality.

I am sending you a formula which is for sure of high quality and it may be good to have it at home.

If you want to use it on a regular basis [2x per week one -even if you are healthy- fine]. In case of disease, you may ask me how to use it or or follow the bottle instructions
