Xi-xin is a crude drug using a subterranean portion of a few plants of Asiasarum genus (Asaraceae family). The most important of its component has been reported as methyleugenol which makes up about 50% of its essential oil but this was found to vary greatly according to habitat of the plant. Some plants contained safrole, eucarvone, and 1, 8-cineol as the chief components. Xi-xin oil from Manchurian plant was proved to contain elemicin, an isomer of cis-asaron.Tu-xi-xin is the dried root of Hetehotropa genus of the same family and used as a substitute for Xi-xin. The chief component of its essential oil had been reported as safrole but elemicin was found to be present as the chief component in some of the crude drug.

A clear distinction between Tinnevelly Senna and Alexandrian Senna by histological anatomy was found. The best way to find the distinction is the comparison by the degree of development of fibres in bundle of the costa. For that purpose, the leaflets of about 2 cm. in length were used. It was no good to use the leaflets less than 1 cm. and more than 3 cm. in length. We got positive proofs that the anatomical figure of Tinnevelly Senna after A. Tschirch which had been quoted in many textbooks of Pharmacognosy is not typical. It was characteristic of Italian Senna and Aden Senna that both their costa are not prominent under the leaflets and the cell wall of the base of hair is not so thick.
