Pithecellobium dulce, commonly known as Manila tamarind, Madras thorn, monkeypod tree or camachile,[4][5] is a species of flowering plant in the pea family, Fabaceae, that is native to the Pacific Coast and adjacent highlands of Mexico, Central America, and northern South America.

The flowers are greenish-white, fragrant, sessile and reach about 12 cm (4.7 in) in length, though appear shorter due to coiling.

In its native Mexico, the tree is known as huamuche, guamuche, huamúchil, guamúchil, or cuamúchil, deriving from its Nahuatl name cuauhmochitl.

It is known as kamachile in Tagalog (from where the English name "camachile" is derived), kamunsil in Hiligaynon, and damortis or kamantiris in Ilokano.

These include: makham thet in Thai; plaeh umpel tek in Khmer; kona puliyangai in the Kongu region and kodukkappuli in other regions of Tamil Nadu; sīma cintakāya or sīma tummakāya in Telugu; dora hunase or sīme hunase in Kannada; bakhai ambli or goras amali ,katra in Gujarati; vilayati cinc or cinc bilai or cheese bilai in Marathi; jungle jalebi in Hindi;[11] sīma kaiyan in Odia; achi gidamiri in Sindhi; and jilapi in Bengali.

The seed pods contain a sweet and sour pulp which is eaten raw in Mexico, the Philippines,[12] Pakistan, Qatar and India[13] as an accompaniment to various meat dishes and used as a base for drinks with sugar and water ('agua de guamúchil').

[13] The Huastec people of northern Veracruz and San Luis Potosí in Mexico used different parts of the tree to treat gum ailments, toothache and cancer.
