Astragalus is the primary botanical used in Chinese herbalism for supporting immune resistance. Not all astragalus is alike; its quality can range from extremely low to higher grade. Planetary Herbals Full Spectrum Astragalus is prepared from premium grade astragalus roots to insure all the primary compounds of astragalus are present.

Full Spectrum Astragalus Glycerite is prepared from the same premium grade astragalus as the Planetary Herbals alcohol extract. In order to capture the full range of constituents, the herb is first extracted in alcohol. The alcohol is then slowly evaporated off at a low temperature and reconstituted with pure vegetable glycerine. Glycerine extracts such as these are ideally suited for children or those wishing to avoid alcohol.
