  1. SE Asia / Oceana Cymbopogon citratus – Victor Castillo Melaleuca alternifolia – Christina Castro Aleurites moluccana – Apollonia Mendoza Piper betle – Jacklyn Vicente Biology 454L – Medical Ethnobotany CSULA Fall Quarter 2010

  2. Cymbopogoncitratus

  3. Taxonomy and Ecology Scientific Name: Cymbopogon citratus Order: Poales Family: Poaceae Common name(s): Lemongrass, barbed wire grass, silky heads, oil grass. Lemongrass is a tall, perennial, aromatic grass that is native to the tropical regions of South East Asia, especially India. Has a branched cluster of stalked flowers and leaf blades. Can grow up to 6’ tall. It is one of about 55 species of grasses

  4. Traditional Uses For Lemongrass Thailand, Vietnam, Indonesia, Malaysia:, India: It is one of the most important flavorings used for cooking due to its Citral oil, which gives a sour lemon flavor and aroma. Used fresh, dried, or powdered leaves Philippines: Root, stem, and leaf are boiled in water in order to separate the lemongrass oil. Such oil is mixed with coconut oil. This oil mixture is widely used in aromatherapy. India: Boiled leaf oil used to treat bacterial and fungal infections as well as fever. Brew of water and leaves is used as an antiseptic, antitussive, and anti rheumatic. South America: Widely used in folk medicine as an antispasmodic, analgesic, anti fever, and antiemetic. Also treats flatulence, nervous and gastrointestinal disorders by drinking a brew of leaves and water(abafado). China: Brew of leaves and water is used to treat abdominal, head, stomach, and rheumatic pain. The very few experiments done on Lemongrass only credit the antifungal properties of Lemongrass.

  5. Modern Uses For Lemongrass Cosmetics and Home/Cleaning Products: Lemongrass oil contains myrcene, (7-Methyl-3-methylene-1,6-octadiene). Due to its fragrant lemon aroma and volatile properties, lemongrass oil is used in soaps, candles, hair care products, home cleaning products, and perfumery. Pesticide aerosols, insect repellents, flavorant: Lemongrass oil contains citral, (3,7-dimethylocta-2,6-dienal). This compound has pheromonal effects on insects and is therefore used as a natural pesticide. When burned, the oil serves as insect repellent. Citral’s strong lemon taste and very low toxicity make it a suitable flavorant for human consumption. Homeopathic Medicine: Although the exact mechanism of action is not known, Lemon grass oil and dried leaf powder is used to treat asthma, bladder disorders, coughs, headaches, excessive sweating, acne, and athlete’s foot. Allopathic Medicine: No pharmaceutical derivatives exist that have been approved by the FDA. Citral, found in lemongrass oil, is currently being researched in Israel as a potential cancer cure as is causes apoptosis in cancer cells. Lemongrass oil is extracted from the leaves and stems using distillation
