Summary
Source: WikipediaAilanthus triphysa (also Ailanthus malabarica), ferntop ash, is a medium to tall evergreen rainforest tree that is native to Asia and Australia. The wood is used for matchwood and plywood. The tree is known as halmaddi in India, where its resin, also called halmaddi, may be used in incense. Inappropriate extraction methods were resulting in trees dying, thus by the 1990s the Indian forestry department had banned extraction.

Medicinal Uses
The wood is yellowish and brittle; the timber is mainly used for matchwood and plywood, though also makes charcoal. and When the bark is cut, a sticky resin is exuded, which becomes brittle on drying; this resin may be used for medicinal purposes, and particularly, because of its fixative properties, it may be used an ingredient in incense sticks. In India, the incense resin is named halmaddi, after the local name for the tree itself. Due to crude extraction methods which resulted in trees dying, by the 1990s the Forest Department in India had banned resin extraction; this forced up the price of halmaddi, and its use in incense-making declined. In Cambodia, the resin is also used as incense, whereas the bark is used in local folk medicine against dysentery and intestinal œdema. The wood contains various alkaloids and quassinoids, including beta-carboline, and has been used for the treatment of dyspepsia, bronchitis, ophthalmia and snake bite.

The yellow wood is light in weight, soft and porous. It is used for making boats, matches, fishing floats and weaponry accessories such as sword handles and spear sheaths. The leaf litter decomposes well to help restore soil fertility. The trees are used to act as supports for growing plack pepper (Piper nigrum).
