hello,
For an accurae description see the MBG tropicos site Flora of China
at the following url (direct for the taxon):
mpwg at lists.plantconservation.org
The confusion is grounded by the fact that Gentianine (a compound
quite close to gentiopicroside) has been reported in the plant
(Rakhmatullaev, T.U. 1971 Alakaloids from gentiana olgae, Gentiana
vvedenskyi, Gentiana tanscianica (sic), and Swertia connata,
Khim.pri. Soedin. 7:128
The fact is that as far as tibetan medicine is concerned there is not
such a thing as one name = one species. Over time and as the tibetan
medical system extended over a huge territory, plus due to the fact
that an oral tradition of teaching has always been part of the
system, the tibetan doctors have adapted to different floras and
developped alternative options for the plants they could not (or with
difficulty) find in a given area. So "substitutes" so to call are a
very common feature of the tibetan medicine pharmacopeia.
The current trend in scientification and the political situation are
currently reducing this feature with the development in the official
teachings of a one plant-one species reference corpus. The Men Tsee
Khang current identifications are, thus, marked by the new
localisation in India and tend to rely on indian himalyan or nepalese
species (western himalayan), rather than tibetan and China
authorities develop their own identifications (obivously derived from
eastern himalayan species).
