Wathusudda (Crape Jasmine): The Delicate White Flower for Eye Health

Botanical and Cultural Overview

Wathusudda (Tabernaemontana divaricata), commonly known in English as Crape Jasmine, Pinwheel Flower, or East Indian Rosebay, is a beautiful evergreen shrub belonging to the Apocynaceae family. Native to South Asia, it is one of the most common ornamental plants in Sri Lankan home gardens, heavily cultivated for its glossy green foliage and brilliant white, mildly fragrant flowers that bloom year-round. While admired primarily for its aesthetic appeal, Wathusudda holds a secret identity as a potent medicinal plant in traditional Ayurvedic and folk medicine. The entire plant, particularly the flowers, leaves, and the milky white latex (sap) it produces when cut, is utilized to treat ocular, dental, and dermatological ailments.

Key Medicinal Uses

1. Treating Eye Infections and Conjunctivitis

The most famous traditional use of Wathusudda is in eye care. The pristine white flowers and the milky sap possess remarkable antimicrobial and anti-inflammatory properties. In rural folk medicine, a highly diluted and specially prepared extract from the flowers is used as an eye drop to treat conjunctivitis (pink eye), soothe irritated eyes, and clear vision. (Note: Extreme caution and expert knowledge are required before putting anything into the eyes).

2. Relief from Severe Toothaches

The roots and the milky sap of the Wathusudda plant contain natural analgesic and anesthetic compounds. A tiny piece of the root is traditionally chewed, or a drop of the milky latex is carefully applied directly to a decaying tooth cavity to instantly numb the nerve and relieve agonizing toothaches.

3. Wound Healing and Skin Eruptions

The milky sap (latex) is an excellent topical antiseptic. It is applied to minor cuts, scrapes, and scabies to prevent infection and promote healing. Furthermore, a poultice made from crushed Wathusudda leaves is highly effective in drawing out pus from boils, abscesses, and pimples, aiding in their rapid resolution.

4. Anti-inflammatory for Joint Pain

The leaves possess strong anti-inflammatory properties. Warming the leaves and tying them over sprained joints or rheumatic swellings helps reduce pain and edema significantly.

5. Anthelmintic Properties (Deworming)

In certain traditional practices, a mild decoction of the roots or leaves is administered internally to expel intestinal parasitic worms, particularly in children.

Preparation Methods

• For Toothaches: Carefully extract a single drop of the white latex from a broken stem or leaf and apply it directly onto the aching tooth cavity using a cotton swab.
• For Boils and Abscesses: Crush a handful of fresh Wathusudda leaves to a fine paste. Apply this poultice over the boil and wrap it with a cloth to draw out the infection.
• Joint Pain Poultice: Lightly coat the leaves with oil, warm them over a flame, and bandage them over swollen or painful joints.

Safety and Precautions

While externally beneficial, Wathusudda belongs to a plant family known for toxic alkaloids. The milky sap can be mildly irritating to sensitive skin, and internal consumption of the plant must be strictly avoided unless prescribed by a qualified Ayurvedic physician. Applying traditional remedies to the eyes carries significant risk; the sap or flower extracts should never be put into the eyes without the preparation and supervision of an expert traditional eye specialist, as incorrect dosage can damage the cornea.
