Astragalus, Milk Vetch, Huang Qi (Chinese) (Astragalus membranaceus) - Recent
American research has focused on the ability of astragalus to restore normal
immune function in cancer patients. Clinical evidence suggests that, as with
a number of other herbs, cancer patients undergoing chemotherapy or radiotherapy
recover faster and live longer if given astragalus concurrently. It raises
immune resistance and manifestly improves physical endurance perhaps even
superior to ginseng. Astragalus is often combined with angelica (Angelica
sinensis) as a blood tonic.
Pau D'Arco (Portuguese), Lapacho (Spanish) (Tabebuia spp.) - Research
in Brazil, which started during the 1960s, indicates that the bark is
therapeutically useful in treating cancer, including leukemia. Many of the
herb's constituents play a part in counteracting the growth of tumors, notably
lapacho, which inhibits the growth of tumor cells by preventing them from
metabolizing oxygen.
Ashwagandha (Hindi) (Withania somnifera) - Research in 1970 showed
that withanolides are anti-inflammatory and inhibit the growth of cancer
cells. Trials in 1980 indicated that ashwagandha increases hemoglobin levels
and helps recovery from chronic illness. It has a high iron content and is
used as a restorative for the elderly and chronically ill. Its sedative action
calms and strengthens the nerves, and encourages restful sleep, making it
useful for countering the debility that accompanies long-term stress.
