The present invention relates to a process for providing non-lipid, liquid form herbal extracts in a vegetable gelatin, HPMC, or any other cellulose derivative capsule. The process includes extracting an herbal plant material with an alcohol to provide an aqueous alcoholic herbal extract. The aqueous alcoholic herbal extract is contacted with sufficient glycerin to maintain the extract preferably in solution, and at least dispersed in the mixture of glycerin and aqueous alcoholic herbal extract. Alcohol and water is removed form the mixture to provide a glycerin-based liquid or semi-solid herbal extract and having a moisture content of less than 10 percent by weight, and preferably less than 5 percent by weight. The herb extract is then encapsulated in a vegetable gelatin, HPMC, or any other cellulose derivative capsule.
