335. +Senna.+ The leaves of Cassia lanceolata, _Forsk._, and other species. Indian or Tinnevelly Senna. Saná, Hindí-saná-ká-pát (_Hind._), Nát-kí-saná (_Duk._), Són-pát, Shín-pát (_Beng._), Sanna-mákhí (_Punj._), Berg-i-sanna (_Kash._), Nilá-virai, Níla-vakái (_Tam._), Néla-tangédu (_Tel._), Níla-váká (_Mal._), Nelá-varíke (_Can._), Sana-kola, Nil-ávari (_Cing._), Puve-kain-yoe (_Burm._), Sunna Maki (_Malay_). 336. The imported Senna met with in the bazaars is usually of very inferior quality, consisting of broken pieces of old leaves, pieces of stem, and other rubbish. That grown in India, especially in Tinnevelly, is preferable to that imported from Arabia, which is called _Sana-Makhí_, or _Mecca Senna_. The leaves should be unbroken, clean, brittle, pale green, or yellow, with a heavyish smell. It is a good safe aperient, and may be given as follows: Take of Senna leaves, one ounce; of bruised Ginger and Cloves, each half a drachm; Boiling Water, ten ounces. Let it stand for one hour, and strain. This is a good aperient in all cases of _Constipation_, in doses of one and a half to two ounces; half this quantity, or less, is required for children, according to age. A simple infusion of Senna leaves, of the above strength, if taken hot, with the addition of milk and sugar, can hardly be distinguished from ordinary tea. In this manner it is easily administered to children, and will be borne by the most delicate stomachs. As a general rule. Castor Oil is preferable as an aperient for infants. 337. +Sesamum+, +Jinjili+, or +Til Oil+. The expressed oil of the seeds of Sesamum Indicum, _Linn._ Til-ká-tél, Míthá-tel (_Hind._, _Punj._), Mittá-tél (_Duk._), Nal-enney (_Tam._), Manchi-núne (_Tel._), Nall-enná (_Mal._), Valle-yanne (_Can._), Chokhóta-téla (_Mah._), Mítho-tél (_Guz._), Talla-tel (_Cing._), Tíl (_Kash._), Nahu-sí (_Burm._), Miniak-bijan (_Malay_). 338. Til or Jingili Oil, met with in all bazaars throughout India, is quite equal, when properly prepared, to Olive Oil for medicinal and pharmaceutical purposes. It is advisable always to keep a small stock of it on hand for cases of emergency, such as burns, &c., when Lime Liniment (229) may be required. As a dressing for _Ulcers, Suppurating Wounds_, "oil dressing" has been successfully applied in Bombay; it consists of the continuous application of a pledget of common country cloth or rag saturated with pure Sesamum Oil to the affected part. It is thought to be superior to any other simple dressing particularly during the hot season. _In Leprosy_ Dr. Hilson has conclusively shown that great and manifest benefit, though it may be temporary, results from diligent frictions of the body with this oil (see Sect. 161).
