Tabernaemontana coronaria is a member of the Apocynaceae family., It is a glabrous, evergreen shrub that reaches up to 3m high. The bark is silvery grey and has milky latex. The leaves are simple, opposite, elliptic or elliptic-lanceolatye, sweetly fragrant in 1-8 flowered cymes at the bifurcations of the branches.

The seeds are dull brown, minutely pitted, irregular, and enclosed in a red pulpy aril. [2]

Roots, flowers and latex. [1][2]

Traditional Uses

Traditionally the roots of T. divaricata is considered acrid, bitter, thermogenic, anodyne, astringent, vermifuge and tonic. The flowers and latex are cooling with fragrant and anti-inflammatory respectively [1][2]The latex being anti-inflammatory in nature is often applied on wounds to promote healing. It is also used in treating the stye [5].

The plant had been used effectively to treat various forms of ophthalmia like acute and chronic conjunctivitis where the juice, squeezed out from the leaves, is dropped into the affected eye. A poultice made from the leaves is applied over mastitis and pyoderma and the decoction can be used in high blood pressure treatment [2][5].

The bitter roots are used to treat diarrhoea, sore throat, bone fracture and relieve toothache. It also used in combination with other herbs to treat  intestinal worm infestation, kidney problems, urinary stones and tumour.[5]

Pre-Clinical Data



The indole alkaloid, vVaocristine, isolated from T. divaricata exhibited cytostatic and cytotoxic activities detected in the culture of Saccharomyces cerevisiae and occurs exclusively in growing cells. The lesions induced are probably of the adducts type which is reparable in the wild-type. [9][10]
