Design and evaluation of San-huang dispersible tablet--an efficient delivery system for Traditional Chinese Medicine.

San-huang dispersible tablet (SHDT) was designed with a patented technology to enrich the active ingredients in rhubarb and with a wide selection of excipients in the new manufacturing procedure. The total rhubarb anthraquinones were first enriched in the extract by our patented technology. Eudragit L100, S100 and PEG-6000 were used to release a part of the total rhubarb anthraquinones at the colon to induce the cathartic effect of the anthraquinones by another patented technology.
