Pain relief is a tall order for a tincture to fill but the tincture made by Alta California Botanicals can deliver the goods. It is novel in that the amount to use is based on your weight—which is actually how any tincture should be administered. One drop for every 100 pounds. Even though it uses THCA (Tetrahydrocannabinolic acid) as its major active ingredient, there is a mild head rush shortly after putting the requisite number of drops under your tongue. There is an alcohol taste at first that quickly dissolves into a very pleasant, sweet honey taste. It is very fast acting with an almost immediate body effect. Definitely a high-quality product.
