Traditional Used:

Gastrointestinal Diseases

In the Philippines the bark of H. tiliaceuas is used to treat diarrhea by drinking the water where the fresh bark had been soaked. [1] The slimy substance expressed from the bark or flower bases are laxatives for the Hawaians. [4] Infusion of the bark is taken as a potion for treating stomachache. [8]

Respiratory Diseases

The Malays of costal Peninsular Malaysia used the leaves as an aid to remove phlegm from the respiratory passages. [1] Bark together with other plants crushed and water is added, strained and the resulting liquid taken for congested chest. [4]

Obstetrics and Gynaecology

The flowers are used as contraceptives while the slimy substances from the inner bark mixed with water is given to ease childbirth both in Hawaii [4] and the Pacific Islands. [7]

Other Uses

Leaves are used medicinally to treat broken bones, torn ligaments and sprains. [6] In the Tonga Islands mucilage from the bark is dripped into the eye to treat eye infection and injuries. [8]

Pre-Clinical Data

Pharmacology

Cytotoxic activity

Chen et el. [2] isolated a new amide from the stem wood of H. tiliaceuas which proved to have cytotoxic activities against P-388 and HT-29 cell lines in vitro.

Tyrosinase inhibitor activity

Masuda et al. [10] found that extracts of H. tiliaceuas had potent activity against tyrosinase.

Antioxidant and Antimutagenic activities

Rosa et al. [11][12] studied the antioxidant and antimutagenic activity of H. tiliaceuas using methanolic extracts of the flowers had shown that these extracts strongly inhibit the mutagenic action of H2O2 or tert-butyl-hydroperoxide (t-BHP). They also demonstrated the this extract had cytoprotective effects by preventing GSH depletion and lipid peroxidation by H2O2 and t-BHP.
