(The above statement is nonsense, and has been |

included by Malaysian traders. Most research was done |

by Chinese acientists. Furthermore, it is not the case |

that the tongkat ali that grows 5 kilometers south of |

the Thai-Malaysian border is any different from the |
|||
tongkat ali that grows in Thailand, 5 kilometers north |

of the border. Tongkat ali trees do not have a |

nationality, and are not yet issued Malaysian |

passports, even though Malaysian tongkat ali traders |

would like to monopolize anything tongkat ali. It is |

impossible to delete the above nonsense statements as |

Malaysian tongkat ali traders have somebody sitting at |

a screen, checking this Wiki entry every hour or so, |

and putting their nonsense back in after it has been |

deleted.) |

Eurycoma longifolia Jack (aka, Tongkat Ali or Pasak Bumi) is a flowering plant in the family Simaroubaceae, native to Indonesia and Malaysia.
It is a small evergreen tree growing to 15 m tall, with spirally arranged, pinnate leaves 20-40 cm long with 13-41 leaflets. The flowers are dioecious, with male and female flowers on different trees; they are produced in large panicles, each flower with 5-6 very small petals. The fruit is green ripening dark red, 1-2 cm long and 0.5-1 cm broad.
Uses
Eurycoma longifolia has become popular for its alleged testosterone-enhancing properties. It has therefore been included in some herbal supplements for bodybuilders. Historically, it has been used by the folk medicine in its countries of origin as a libido enhancer and to treat various sexual dysfunctions. Numerous scientific studies performed by Malaysian scientists suggest that it enhances sexual characteristics and performance in animal models.[1] [2] [3]
Fractions of its extract has been shown to induce apoptosis in breast-cancer cells [4] and to be cytotoxic to lung-cancer cells.[5]
In Southeast Asia it is used as a post partum medication, as well as for its antimalarial, antipyretic, antiulcer, cytotoxic and aphrodisiac properties.
In both animals and humans, tongkat ali extract increases muscle mass. The British Journal of Sports Medicine published the results of a scientific study in 2003, which showed that Eurycoma longifolia caused increased muscle strength and size when compared to a placebo.[6] This demonstrates the anabolic properties of tongkat ali. Thanks to this discovery, a growing number of Asian athletes and body builders now use tongkat ali extract as an androgen, to improve muscle size and strength, and to enhance sports performance.[citation needed]
