Back To Our Roots: Traditional Medicine In Sarawak

Did you know that eating black pepper was beneficial for the heart and could help to prevent tooth decay on top of it being used widely to season food? How about Serai or lemongrass being used as a painkiller?

Sarawak’s forests hold over 1,000 known plant species with medicinal properties. Many of these plants have been traditionally used by various indigenous communities to treat a variety of illnesses.

The traditional practices are easy to learn. Many of the techniques involve pounding the plants’ roots (rhizome) or leaves. This increases their potency. The pounded roots and leaves are then made into a poultice and applied over an affected/injured area on the body.

Let’s look at some common medicinal plants found in our forests and gardens that hold many healing attributes and are used by indigenous communities in Sarawak.

Alpinia galanga Lengkuas
(Malay, Iban), engkuas (Iban), lacos (Bidayuh) and la’ku’er (Kelabit)

This ginger plant (known as galangal in English) is a staple ingredient in many curry dishes. The plant grows up to 1.5 metres tall and is widely cultivated in villages or grown semi-wild near villages. The leaves grow up to 48cm long, 6.5cm wide and are not hairy. Inflorescence at the end of the leaves and up to 28cm long. Flowers are whitish, V-shaped and deep purple at two lower petals.

The Iban folks use galangal to remedy itches by means of pounding it along with a bit of salt before applying the mixture onto the skin. To reduce fever, the Bidayuh crush the leaves and stems of the galangal, boil them then use the water to bathe. To help mothers feel vitalised after childbirth, the Kelabit drink galangal tea for energy.

Curcuma domestica
Kunyit (Iban, Kayan, Malay), kunyit likau, kunyit putih, penawar (Melanau)

Turmeric or kunyit is a very common plant found in our rainforests. Cultivated to over one metre tall, turmeric is a ginger plant best characterised by its rhizome of distinctive deep yellow hue and aromatic scent. The leaves are oblong-shaped, varying in size and not hairy. Its flowers are white.

This plant is used as a remedy for many ailments. These include treating skin diseases (Iban), headaches (Melanau), detoxing following childbirth (Iban, Malay), drunkenness and coughing (Melanau) as well as asthma (Kayan).

Manihot esculenta
Ubi, ubi kapok, daun jabang (Iban), daun bandung (Melanau), bandong betawai (Selako), itun obek, ubek kayo (Kayan)

A small shrub that is cultivated, this tapioca plant is locally called bandong or ubi kayu. The young leaves are traditionally eaten as vegetables and are now served even in hotels as ‘ulam ulaman’ (local salad) with sambal belacan (spicy tangy dip made with fermented shrimp paste). The plant is easily propagated by stem cuttings and grows in a variety of soils.

Pounded into a pulp, the leaves can be applied as a poultice to mitigate headaches. Bidayuh, Selako and Melanau folks practise this even to this day. The Iban believe that by merely mixing the juices from the leaves with honey and drinking the concoction, their constipation woes will be alleviated. Rubbing the latex onto the skin will relieve swelling. It can also be used as an antidote against rengas poison. The Kayan folks believe that drinking fresh juice from the leaves will stop hematemesis (vomiting blood). They also believe that rubbing its warm bark onto the skin will relieve pains and itches caused by the hairs of caterpillars. For the Chinese, regular intake of the tapioca leaf tea offers protection against cancer of the colon.

It is a shrub or medium-sized tree that grows to a height of 12 metres tall. It thrives in secondary forests and is also cultivated. Its leaves pinnate, leaflets lanceolate or elliptic and are often unequal on both sides, with the veins on the leaves raised on both surface. Its fruit pods are irregularly-shaped, flattened, black and hard. The jering fruit can be easily found sold in markets selling local produce.

The Iban and Malay eat jering either cooked or raw, dipping them in shrimp paste sambal. It is believed to be good for the kidneys and is a remedy for diabetes. It also enhances urine flow, although the urine passed will have a strong smell. The leaves may also be boiled to make tea.

The Iban folks use sap from the leaves to heal open wounds by applying them directly on the affected area. The Iban and Kayan also believe that consuming the guava plant’s young leaves raw may stop diarrhoea. A poultice of the young leaves can be used to relieve stomach-ache. The Malay, Kenyah and Kelabit also use the poultice of the young leaves to treat cuts and wounds. The Melanau, meanwhile, boil the leaves of the guava plant and use that to cure boils and scabies.
