Do tinctures of Salvia divinorum require special storage?
. An ethanolic tincture will retain its potency for many, many years, provided that it is stored in a dark location. Salvia divinorum tinctures are particularly vulnerable to UV light. The salvinorin A in them decomposes fairly quickly when exposed to strong sunlight. Tinctures should be stored at room temperature. They should not be refrigerated because cold temperatures can cause a tar-like sediment to form in the container. Since this sediment contains some of the active principal, the potency of the liquid will be reduced.
