The Malayan designation of the lower part of the stipes of a large Fern indigenous in Sumatra, which has recently obtained some note as a styptic. Mr. Archer refers it to the Cibotium Schiedei of Schleet and Chamisso.
Med. Prop. and Action. As a styptic, Penghawar Djambi, according to Dr. Vinke, possesses the following advantages: - 1. It arrests more quickly than any other pharmaceutical means (agaric, sponge, &c.) Parenchymatous, Venous or Arterial Hmorrhage, provided the diameter of the artery does not exceed one line and a half. 2. It produces a coagulum, even in cases where the blood has changed so much that it has nearly lost the property of coagulating, or where the walls of the vessels are so diseased that they are incapable of a plastic process, e. g. in carcinomatous and scorbutic ulcers. 3. It does not change the vitality of the wound or ulcer, and therefore does not exert an injurious influence on the healing process.
Penghawar acts better when crumbled than when applied entire. Five grains are sufficient to arrest considerable haemorrhage, and more than gr. xx. are never required It is to be pressed for two or three minutes directly on the bleeding surface; after which a bandage or strips of adhesive plaster are to be applied over it, taking care not to draw the wound too closely together. If the bleeding does not proceed from the whole surface of the wound, it is not necessary to fill the entire cavity of the wound or ulcer with Penghawar. The haemorrhage ceases even more rapidly if the Penghawar (in the form of a pencil) be pressed upon the bleeding surface, so that the filaments are directed perpendicularly against it. The internal administration of Penghawar (in hAemorrhage), as recommended by Gaupp and others, is quite useless. In order to retain its efficacy, it should be kept in a dry place, where it cannot absorb moisture. *
