NYMPH.EA LOTUS 27 



CHEMICAL COMPOSITION. Fliickiger has isolated a bitter 

 principle analogous to berberin ; also buxine and paracine, which 

 latter received the name pelosine from Wiggers in 1839. The 

 former chemist proposed the name buxine for all these analogous 

 principles. Pelosine or buxine is precipitated by a concentrated 

 solution of HC1, by sal ammoniac, by potassium nitrate and 

 potassium iodide. He also discovered a neutral substance, 

 deyamitin, which crystallizes in microscopic tablets ; sulphuric 

 acid added to these gives a pretty dark blue color which changes 

 to green. 



BOTANICAL DESCRIPTION. A climbing shrub with cylin- 

 drical woody stem, with leaves simple, alternate, entire, petio- 

 late, ovoid, broad at the base. The inferior surface of the leaf

 ranged in 3 whorls, the inner ones broad and petaloid. Corolla

 mentary in the pistillate flower, the staminate flower bearing

USES. The anaphrodisiac virtues attributed to this plant 

 and to all the water-lily family are purely imaginary. Its juice 

 being slightly bitter and astringent is used in decoction as an 

 injection in gonorrhoea. It possesses mild narcotic properties, 

 for which some use the juice of the whole plant, rubbing the 

 forehead and temples with it to produce sleep.
