Gen info
Schefflera are shrubs or trees, sometimes climbers or epiphytes, usually with palmately compound leaves. Several recent phylogenetic studies have shown Schefflera is clearly polyphyletic, and that the Asian species belong to a single, well supported, morphologically coherent clade, which might have to be transferred to some other genera. (1)

There are nearly 1100 species widely distributed in the tropics and subtropics of both hemispheres; about 5 or 6 species endemic in the Philippines.

Botany
Galamai-amo is a woody vine growing 2 to 6 meters or more. Leaves are palmately compound, smooth, crowded at the ends of the branches, with 7 to 9 leaflets. Leaflets are of different sizes in the same leaf, oblong or oblong elliptic, 10 to 24 centimeters in length, 3 to 8.5 centimeters wide, and upon 5- to 7-centimeter-long stalks, narrowly pointed at the apex and pointed at the base. Flowers are pale white, umbellately clustered upon short stalks, 1 centimeter long, and borne on terminal or subterminal compound inflorescences 15 to 30 centimeters long. Fruit is orange, ovoid, prominently ridged when dry, 7 to 9 millimeters in diameter.

Distribution
- Found only in the Philippines.
- Common in primary forests along streams at low altitudes in Laguna, Quezon, Camarines, Albay, and Sorsogon Provinces in Luzon; and in Mindoro, Masbate, Polillo, Catanduanes, Samar, Leyte, Negros, and Mindanao.

Constituents
- Phytochemical screening of ethanol extracts of leaves yielded alkaloids, phenols, flavonoids, tannins, and terpenoids. (see study below) (4)

Parts utilized
Leaves.

Folkloric uses
• In Mindoro, fresh leaves are pounded and the juice used as purgative.
• Schefflera elliptifoliola or S. insularum is one of the ten indigenous herbal ingredients used in the post-partum ritual of suob. (See: Suob)
• Leaf infusion used as bath for spasmodic pains. (3)

Studies
• Cytotoxic, Antibaterial / Leaves: Study evaluated a leaf extract of Schefflera insularum for cytotoxc, antifungal and antibacterial activity. The extract only exhibited activity against gram-positive bacterium Staphylococcus aureus. Study showed high cytotoxicity on Brine Shrimp Lethality assay. (5)

Availability
Wild-crafted.
