Pokok Saga


  • Scientific name:

    Adenanthera pavonina

  • Other names:

Pokok Saga, scientifically known as Adenanthera pavonina, is a tropical tree native to Southeast Asia, widely recognised for its vibrant red seeds. Beyond its ornamental use and the use of its seeds in jewelry, various parts of the plant have a long history of traditional medicinal applications, and some of these uses are now being explored through scientific research.

Here's a breakdown of the medicinal uses of Adenanthera pavonina:

  1. Seeds:
  • Anti-inflammatory: Traditionally, crushed seeds are used as a poultice to treat boils and inflammations. Scientific studies have also demonstrated the anti-inflammatory activity of seed extracts. This is attributed to compounds like triterpenes and flavonoids which can inhibit prostaglandin synthesis.
  • Pain Relief (Analgesic/Antinociceptive): The seeds, and extracts thereof have been traditionally used for conditions involving pain, such as headaches and rheumatism.
  • Antihyperglycemic/Antidiabetic: Young leaves are traditionally eaten as a salad by diabetic patients to help reduce blood glucose levels. Some studies suggest that seed extracts may help in managing blood sugar.
  • Cholesterol Lowering (Hypolipidemic): Research indicates that seed extracts may help lower blood cholesterol levels.
  • Boils and Ulcers: Powdered seeds are traditionally applied to boils to hasten suppuration (formation and discharge of pus) and aid in healing. Leaf paste is also used on skin wounds and ulcers.
  • Antimicrobial/Antibacterial: Saga seeds have shown antibacterial properties, leading to their use in traditional remedies and even in the development of natural antibacterial soaps.
  • Digestive Aid: In some traditions, bark decoctions are used to manage loose stools, likely due to astringent compounds like tannins.
  • Febrifuge (Fever Reducer): Seeds are traditionally used to treat fever.
  • Antiemetic: Used to treat vomiting and nausea.
  • Aphrodisiac: In some tribal traditions, roasted seeds are consumed in tiny quantities to boost male fertility and libido, though this claim requires more scientific validation.
  • Other traditional uses: Headache, rheumatism, paralysis, cholera, and general weakness.

Important Note on Seeds: While traditionally used, raw Adenanthera pavonina seeds are considered toxic. They contain certain compounds that can be harmful if ingested uncooked. Roasting or boiling is often done to neutralize these toxins when consumed.

  1. Leaves:
  • Anti-inflammatory: Similar to seeds, leaf extracts have shown anti-inflammatory activity, particularly useful for rheumatism and gout.
  • Antidiabetic: Young leaves are consumed as a salad to help lower blood glucose levels.
  • Antioxidant: Leaf extracts possess antioxidant properties.
  • Antibacterial/Antimicrobial: Studies confirm antibacterial activity, especially against Escherichia coli.
  • Wound Healing: Leaf poultices and bark pastes are applied topically for cuts, abscesses, and mild fungal infections.
  • Hypertension (High Blood Pressure): Traditionally used to help regulate high blood pressure.
  • Gout and Rheumatism: Leaf concoctions are taken orally or applied topically for joint discomfort.
  • Urinary Problems (Hematuria): Used to treat blood in urine.
  • Tonic/Vitality: Traditionally considered a general tonic for inner vitality.

 Phytochemicals and Scientific Basis: Scientific investigations have identified various active phytochemicals in Adenanthera pavonina, including:

  • Flavonoids: (e.g., kaempferol, quercetin, apigenin, butein, robinetin) contribute to antioxidant, anti-inflammatory, and potentially anti-cancer activities.
  • Saponins: Contribute to astringent properties and various biological activities.
  • Tannins: Provide astringent and antimicrobial effects, useful for wound healing and diarrhoea.
  • Triterpenoids: (e.g., oleanolic acid, echinocystic acid) known for anti-inflammatory and hepatoprotective effects.
  • Alkaloids: May have diverse pharmacological effects.
  • Fatty Acids: (e.g., linoleic, oleic, palmitic, stearic) found in seed oil.
  • Lectins: Proteins in seeds that modulate immune responses and have shown mild antimicrobial activity.
