              Constituents
                     The chief constituent in Jamaica, Honduras and probably other sarsa-parillas
              is  sarsaponin  C H O .7H O,  a  crystalline  glycoside  yielding  by  hydrolysis
                                44 75 20
                                                2
              sarsasapogenin and dextrose. It is considered as the only definite saponin glycoside
              in Jamaica sarsaparilla, which also contains sarsapic acid (a crystalline dicarboxylic
              acid),  dextrose,  fatty  acids,  sitosterol-D-glycoside,  resin,  etc.  Like  other  drugs
              containing saponins it possesses hemolytic properties of red blood corpuscles just
              hemolysed by 1 g. of the drug. Experiments in this direction have shown that Vera
              Cruz sarsaparilla has the highest hemolytic index, Jamaica rather lower and Honduras
              much lower. The drug yields about 4-10 % of ash.

              Uses
                     Sarsaparilla has been administered as an alternative in syphilis, chronic skin
              diseases and rheumatism, but great' diversity of opinion exists as its therapeutic
              value.

              Varieties
                     Several other varieties of sarsaparilla are imported into the English market.
