You may have seen this in C&E News but for those who missed it:  Danishefsky and co-workers have reported in PNAS on a ginseng analog (poly alkyne) that reduces the side effects of chemotherapy and X-ray treatments.  If you look at the data, then I wouldn’t conclude that the compound drastically improved the side effects of taxol, X-ray and other treatments (3-5% improvement in weight loss, etc), but the idea is interesting and it is a start.
