Contrary to what was expected, although there was a large number of studies published on PubMed on this date, most of them were of fairly low significance, and we decided not to devote a special mention to them. For your record, all studies are also entered in the Alphabetical Herbs page (including those that are not mentioned in daily updates), so if you are interested in a particular herb, you can always go there and check the full list of studies.
We did find one study worthy of separate mention: It reports on important biological activities of a compound from Centella asiatica (gotu kola). See below.
