Durian - Customs and Beliefs

Customs and Beliefs

Southeast Asian traditional beliefs, as well as traditional Chinese medicine, consider the durian fruit to have warming properties liable to cause excessive sweating. The traditional method to counteract this is to pour water into the empty shell of the fruit after the pulp has been consumed and drink it. An alternative method is to eat the durian in accompaniment with mangosteen, which is considered to have cooling properties. Pregnant women or people with high blood pressure are traditionally advised not to consume durian.

Another common local belief is that the durian is harmful when eaten with coffee or alcoholic beverages. The latter belief can be traced back at least to the 18th century when Rumphius stated that one should not drink alcohol after eating durians as it will cause indigestion and bad breath. In 1929, J. D. Gimlette wrote in his Malay Poisons and Charm Cures that the durian fruit must not be eaten with brandy. In 1981, J. R. Croft wrote in his Bombacaceae: In Handbooks of the Flora of Papua New Guinea that "a feeling of morbidity" often follows the consumption of alcohol too soon after eating durian. Several medical investigations on the validity of this belief have been conducted with varying conclusions, though a study by the University of Tsukuba finds the fruit's high sulphur content caused the body to inhibit the activity of aldehyde dehydrogenase, causing a 70% reduction of the ability to clear toxins from the body.

The Javanese believe durian to have aphrodisiac qualities, and impose a set of rules on what may or may not be consumed with it or shortly thereafter. A saying in Indonesian, durian jatuh sarung naik, meaning "the durian falls and the sarong comes up", refers to this belief. The warnings against the supposed lecherous quality of this fruit soon spread to the West—the Swedenborgian philosopher Herman Vetterling commented on so-called "erotic properties" of the durian in the early 20th century.

A durian falling on a person's head can cause serious injuries because it is heavy, armed with sharp thorns, and can fall from a significant height. Wearing a hardhat is recommended when collecting the fruit. Alfred Russel Wallace writes that death rarely ensues from it, because the copious effusion of blood prevents the inflammation which might otherwise take place. A common saying is that a durian has eyes and can see where it is falling because the fruit allegedly never falls during daylight hours when people may be hurt. A saying in Indonesian, ketiban durian runtuh, which translates to "getting a fallen durian", means receiving an unexpected luck or fortune. Nevertheless, signs warning people not to linger under durian trees are found in Indonesia.

A naturally spineless variety of durian growing wild in Davao, Philippines, was discovered in the 1960s; fruits borne from these seeds also lacked spines. Since the bases of the scales develop into spines as the fruit matures, sometimes spineless durians are produced artificially by scraping scales off immature fruits. In Malaysia, a spinesless durian clone D172 is registered by Agriculture Department on 17 Jun 1989. It was called "Durian Botak" (Bald Durian). In Indonesia, Professor Ir Sumeru Ashari MagrSc PhD, Head of Durian Research Centre, Universitas Brawijaya reported spinesless durian from Kasembon, Malang. Another cultivar is from Lombok, Nusa Tenggara Barat, Indonesia.,

Other than humans, animals such as Sumatran elephants are known to consume durian. Curiously, carnivorous Sumatran tiger are also known to consume durian occasionally. The strong odour of the fallen fruits in the jungle probably attracted the tiger to inspect the fruit and lick it.
