Gen info
- Rubiaceae family contains about 13,500 species and 611 genera, consisting of terrestrial trees, shrubs, lianas, and herbs, with a cosmopolitan distribution. Geophila is a small genus of the Rubiaceae family, containing about 30 species.
- Etymology:
The genus name  Geophila derives from Greek ge meaning 'earth', and phileo, meaning 'to love', alluding to the creeping habit of the plant, staying close to the ground.(3) The habit and shape of the leaf blade vaguely resemble the pennywort (Centella asiatica), hence, its common name 'snake pennywort'.
- Taxonomy: Previous name of Geophila repens auct. non (L.) I.M.Johnst, was misused in Asia. The current name of Geophila herbacea (Jacq.) K. Schum. is applicable to all wild plant in Asia and cultivated plants of Asian origin. (3)

Botany
Growth form: A creeping herb, with upright branches up to about 0.08 m tall. Foliage: Opposite, stalked leaves have leaf blades that are heart-shaped, and 1.3–3.8 cm long and wide. Flowers: White flowers are trumpet-shaped, up to 1.5 cm long, and found 1–3 together at the ends of slender stalks. Fruit: Pea-sized fruits are bright orange-red berries with narrow sepals on its tip. (Flora & Fauna Web)

Distribution
- Native to the Philippines. (1)
- In forests at low elevations.
- Also native to  Andaman Is., Angola, Assam, Bangladesh, Benin, Bismarck Archipelago, Borneo, Burkina, Cambodia, Cameroon, Caroline Is., Central African Republic, Chad, China South-Central, China Southeast, Comoros, Congo, Cook Is., DR Congo, Ethiopia, Fiji, Gabon, Ghana, Guinea, Guinea-Bissau, Gulf of Guinea Is., Hainan, India, Ivory Coast, Jawa, Kenya, KwaZulu-Natal, Lesser Sunda Is., Liberia, Madagascar, Malawi, Malaya, Mozambique, Myanmar, Nepal, New Guinea, Nicobar Is., Nigeria, Niue, Samoa, Santa Cruz Is., Sierra Leone, Society Is., Solomon Is., Sri Lanka, Sudan-South Sudan, Sulawesi, Sumatera, Taiwan, Tanzania, Thailand, Togo, Tonga, Uganda, Vanuatu, Vietnam, Wallis-Futuna Is., Zimbabwe.

Constituents
- Assay of ethanolic extract of Geophila herbacea isolated a new compound, 2-phenylethyl 2,6-dihydroxybenzoate. (see study below) (4)

Properties
- Studies have suggested phytoremediative, lipid-lowering properties.

Parts used
Leaves, stems, fruits.

Uses

Edibility
- No report found on edibility.
Folkloric
- No reported folkloric medicinal use in the Philippines.
- Leaves and stems used for treatment of fever, cough, malaria, and other respiratory ailments. Plant used for diuretic effect and for treatment of urinary tract infections. Fruit used for treatment of diarrhea, dysentery, and other digestive problems.(5)
- In Sri Lanka, used for treatment of worm infections in children, rickets, and anemia. Externally, used on sores. (6)
- In Thailand, plant poultice applied to sore legs.
Others

- Agroforestry: Provides for an attractive ground cover. The fibrous root system helps stabilize soil, making it effective for erosion control, especially in areas prone to runoff.

Studies
Natural Lipid-Lowering Compound:
Lipid-lowering assay of ethanolic extract of Geophila herbacea isolated a new compound, 2-phenylethyl 2,6-dihydroxybenzoate. Preliminary dose-dependency verified its lipid-lowering bioactivity in vitro. (4)
Phytoremediation / Removal of Pollutants from Refinery Waste Water / Grass Floating-Bed System: Study evaluated four species of perennial grasses including Geophila herbacea for removal of nutrients and pollutants from refinery waste water. Results showed perennial grass floating-bed system was effective in purifying refinery waste water during growing season, and the harvested perennial grass had great value as animal feeds. (7)

Availability
- Wild-crafted.

                                          New plant names needed
The compilation now numbers over 1,500 medicinal plants. While I believe there are hundreds more that can be added to the collection, they are becoming more difficult to find. If you have a plant to suggest for inclusion, native or introduced, please email the info: scientific name (most helpful), local plant name (if known), any known folkloric medicinal use, and, if possible, a photo. Your help will be greatly appreciated.
