Effect of Trisetum flavescens P.B. on calcium and phosphorus metabolism in rats. Experimental evidence for the principle actively affecting phospho-calcium homeostasis.

After reviewing the literature on the vitamin D3-like activity of certain plants [Solanum malacoxylon, Cestrum diurnum and Trisetum flavescens], the authors present results of experiments in which dried Trisetum flavescens was administered perorally to rats. The addition of 2.5% dried Trisetum flavescens to the standard laboratory diet caused a drop in blood phosphate levels and a simultaneous marked increase in the calcium and phosphorus content of bones of the experimental animals. The mechanism of the action of Trisetum flavescens on phosphocalcium metabolism is discussed.
