General Information

Description

Arenga pinnata is a member of the Palmae family in the Caryoteae tribe and subfamily of Arecoideae. It is a tree that can reach 15m high with a solitary stem up to 0.5m diameter of measurement. The remains of the old leaf sheaths cover the stem with a dense coat of dark brown fibres and spines. The induplicate, pinnate leaves are erect, measuring nearly 10m long and dark-green leaflets measuring 100cm or more with a white waxy coating on their underside. The stout petioles measure 1.5–2.0m long and covered with fibre. The leaflets are about 1m long, 5-8cm wide, and usually with jagged fishtail tips. The large pendent inflorescence emerge from the leaf axils sequentially from bottom to top, consisiting of many long, slender rachillae drooping from a short peduncle. Typically, the flowers are arranged in a triad of two stamina flowers flanking a central pistillate flower, but unisexual inflorescence are sometime produced, especially those developing in the upper axils. The flowers are stalkless and purple, sometime scented. The ovoid fruit is 5–6cm in diameter, yellow to yellowish brown with a fleshy white mesocarp that is irritation to the skin. Each contains two to three grey-brown seeds, 2.5–3.5cm long and 2.0–2.5cm wide.[1]

Traditional Used:

The half-ripe fruit of A. pinnata is considered poisonous and it is usually avoided by natives of the rainforest. There is a high level of calcium oxalate crystals in the seed-coat. However, the seeds itself is much revered by the Malay population especially during the month of ramadhan (biji kabong). To avoid poisoning the fruit wall is removed and the seeds repeatedly washed. The endosperm is then soaked in lime water for a few days and then boiled in sugar solution.[1]

In Malaysia, the young roots in the form of a decoction are used in the treatment of kidney stones while the old roots are chewed on to help relieve toothache. A number of reports mentioned that the use of the decoction of the roots as a remedy for bronchitis, an aid to digestion and improvement of appetite.[2] [3]

The fibres from the stem and petiole are considered styptic, and are used as a haemostatic and cicatrizant to wound. The Filipinos considered it is as diuretic and antithermic treatments.[2]

The juice of the ripe fruit is used as a fish poison and can’t be consumed.[1]
