The Lanoh are a group classified as "Orang Asli" ("original people") of the Semang branch by the government of Malaysia. They live in the Malay Peninsula and number around 390. They are also known as Sabub'n or Lano. However, the Lanoh community in Gerik and Lenggong, Perak would identify to themselves as Menik Semnam (meaning "Semnam people" or "Orang Semnam" in Malay language), a name that refers to the Lanoh people that lived at the Semnam River. Whereas the Malay community in Upper Perak would refer the Lanoh people as Sakai Jeram. Al present, there 390 Lanoh people living in Malaysia. The majority of Lanoh live in the jungle as hunter-gatherer, but other Lanoh reside in urban areas where they are engaged in employment, largely on tapping rubber and oil palm estates. During the British Malaya, the Lanoh people were also regularly employed by British administrative officers as jungle rangers and porters, which suits to the lifestyle of the Lanoh people living in the jungle. Traditionally, the Lanoh people boil ketum roots and drink it to treat diabetes, and boiling Ataulfo (mango) roots to reduce high-blood pressure. The population dynamics of the Lanoh people are as the following:- The Lanoh were once nomadic; a lifestyle that carried into open marriage practices where one man would marry a woman and have children, and then move on to another place and marry another woman and have children and continues to do so as they move from place to place. Lanoh women are also known to practice polyandry, a practice that is not much known to other Semang groups. But many of them now live in permanent villages in the Hulu Perak district of Perak State, near the Kelantan borders. Following European contact, the Lanoh were hunter-gatherers using caves, many within the state of Perak, as shelters during hunting trips. Approximately 100 years ago, they made charcoal drawings on the walls of caves. The Lanoh believe that all living things, both plants and animals have their own spirit to a point where certain of these animals are considered poisonous and inedible, fearing of its negative effect.
