An herb or compound that acts to increase the effectiveness of other medicinal herbs. The term is derived from derived from the Latin word adjuvare, which means to help.

An adjuvant herb is added to a formula of other herbs so as to aid in the distribution of the healing benefits to the targeted location in the body. It also acts to enhance the effect of the other principle herbal ingredients in the remedy.

Adjuvant Herbs

  • Astragalus (Astragalus propinquus)
  • Ginseng (Panax ginseng)
  • Polygala (Polygala tenuifolia)
  • Turmeric (Curcuma longa)

Herbs may also be used as adjuvant to conventional medicine. Several clinical studies report the beneficial effects of using medicinal herbs as adjuvants for conventional cancer therapy. When these herbs are used in combination with chemo- or radio-therapy, they help enhance survival, immune modulation, and the quality of life (QOL) of cancer patients.


In the video below, Dr. K. F. Cheng discusses how medicinal herbs can be used as adjuvants to conventional cancer therapy, to improve the efficacy of the therapy and reduce side effects and complications.
