Introduction of Radix Rehmanniae extract:
A Chinese classic herbal formula. In Japanese kampo, it is known as "(it is also known as Kampo #48). It is commonly made into Chinese patent medicine. It is composed of two famous formulas which tonify the blood (si wu wan) and the qi (si jun zi wan) plus the addition of huang qi and rou gui.
Digitalis is a chemical known as an alkaloyd. These nitrogen containing substances are what many pharmaceuticals are based on. One of their characteristic properties is how their soluability is affected by pH. In acid environments they form alkaloyd salts and are water soluable. In a basic environment they are nonpolar compounds and are soluable in nonpolar solvents. Extraction involves exposing dried plant material to a basic solution of Sodium or Potassium hydroxide in a separatory funnel. To this is added a nonpolar solvent like hexane or petroleum ether. The alkaloys will pass from the water into the nonpolar solvent. The solvent is separated and when evaporated, the alkaloyds remain as a sticky white substance. Alkaloyds are characterized by a bitter taste. Most of these compounds have either stimulatory or sedative effects on the central nervous system and can be toxic in large doses. Digitalis itself is used as a heart stimulant.
