Fig.- The Saul tree (Eng.)
The Sāl tree, called in Sanskrit Sāla and Asvakarna, is of interest from a mythological point of view, as the mother of Buddha is represented as holding a branch of the tree in her hand when Buddha was born, and it was under the shade of a Sāla tree that Buddha passed the last night of his life on earth. The small branches of the Sāla are used by Indian villagers to detect witches; they write the name of every woman over 12 years of age in the village upon a branch; the branches are then placed in water and left for 4 1/2 hours; if any woman's branch withers, she is the witch.
This tree is very widely distributed throughout India, and is undoubtly the source of the Rosin or Rāl of Hindu and Mahometan writers on Materia Indica. Rāl, in Sanskrit Rāla and Sāla-veshta, is regarded by the Hindus as attenuant, detergent, and astringent, and is sometimes prescribed internally mixed with sugar, honey or treacle; as resin does with us, it enters into the composition of stimulating plasters and ointments; it is also used for fumigating rooms occupied by the sick. The seeds of the Saul tree are eaten in times of scarcity with Mahwa flowers by the wild tribes of India. Mahometan writers give a similar account of its properties and uses. The author of the Makhzan-el-Adwiya (vide article Kaikahr) notices the fact that more than one kind of Rāl is met with, but names the Sakoh or Sāl as the source from which the genuine article is obtained. In another part of his work (vide article Sakoh) he describes the tree, and says that when old the bark becomes separated from the trunk by the deposit of Rāl beneath it. Ainslie mentions three kinds of resin or dammar as common in the bazaars of Southern India, but is in doubt as to the sources from whence the different kinds are obatained. He observes that a great portion of the dammar used in India is imported from Java, Bornea, Joanna, and several of the Soloo Islands. The author of the Bengal Dispensatory, after conducting a series of experiments with genuine Sāl resin, pronounced it to be an efficient substitutw for pine resin. In Bombay, at the present time, American resin is to a great extent displacing Indian Rāl. Dr. Sakharam Arjun states (Bomb. Drugs) that he has seen Shorea resin mixed with sugar, given with good effect in dysentery. The oil of the seeds is extracted in Malabar. In the Wynaad Shorea Talara, Roxb. (S. laccifera, Heynne), yields a fragrant resin, known as Sambrani, which is burnt as an incense.
