Herbal extracts take the guesswork out of wondering if an herb has lost its potency after sitting around too long in a warehouse; or after being ground, when herbs can rapidly begin to break down.
Liquid extracts go right into the bloodstream, so that the process of digestion is eliminated. With capsuled herbs there is a question of some herbal properties and constituents being lost in the process of digestion; particularly for those with poor digestion and assimilation.
The dosage of liquid extracts can be carefully controlled by the drop, for those who are sensitive to the actions of herbs.
