Botany. Native to India, it is indigenous to Southeast Asia, especially prevalent in Polynesia. It was naturalized to Hawaii. It was sacred to Polynesians and mentioned in many old Hawaiian chants. Grows to 60 feet with seeds that are dispersed by bats and by sea movement. Seeds germinate well in muddy and saline soils. The tree can grow inland, but favors the coastal areas. In fact, Polynesian natives prefer coastal Tamanu for therapeutic uses. The full grown tree has a thick trunk covered with black, cracked and gnarled bark, with big, twisted branches. It has firm, dark green oval shiny leaves and produces small white flowers with a yellow center, that have a sweet aroma, reminiscent of lime. The fruit is apricot sized, yellow, and apple-flavored covering a large, thick-shelled nut with a pale yellow kernel. This nut, when freshly harvested, seems to have no oil. Once dried for about a month, it turns dark, chocolate-brown and develops a sticky rich oil. The oil is screw-pressed from the dark kernels. Chemistry of the Oil. The oil is cold-pressed from the fruit and seed together. It contains a unique fatty acid called Calophyllic acid and an interesting antibiotic lactone which is a non-steroid anti-inflammatory agent 4-phenyl coumarin called Calophyllolide as well as stigmasterol and about 7% wax. The oil contains 3 basic classes of lipids; 92% neutral lipids, 6.4% glycolipids, and 1.6% phospholipids. It also contains xanthones of jacareubin which inhibits Staphylococcus aureus, S. typhimurium and calophyllum B. These xanthones inhibit P. aeruginosa and Bacillus subtilis. Other components calanolide A and Costatolide are coumarins which inhibit HIV reverse transcriptase. The components of balsam, Calophyllolide and Calophyllic acid contained in the oil are thought to be connected to its curative effects.

History. This tree was once considered a sacred tree by the tropical people and was planted surrounding royal marshes. When the areas were converted to Christianity, the population of the trees dropped by the thousands. It has many names, called Dilo oil from the nuts and the nuts are called Punnai Nuts in Hawaii. The nuts are also collected in Ceylon. In Madagascar, this oil is called Foraha or Vintanina. Properties. Antibacterial, anti-inflammatory, cicatrize, anti-neuralgic, analgesic.

Use. The oil is analgesic and is used for sciatica, shingles, neuritis, leprous neuritis and rheumatism. The pulverized seeds have been used to cure ulcers and bad wounds. Bark also has medicinal uses as an infusion or in other herbal remedies.

Folk or Older Uses. Calophyllum oil has been an important part of Pacific Island folk medicine for a wide range of skin disorders and conditions, from superficial burns and scrapes to neuralgia and fissures. Polynesian woman have used Calophyllum oil to promote healthy, blemish-free skin. It is also used on babies for diaper rash and skin eruptions. This nut oil has been used since the late 1920's to alleviate leprous neuritis . A nun in the Society of Mary, Sister Marie-Suzanne, used an oil called "dolno" (meaning, no pain) effectively on leprosy victims. The oil was Oil of Calophyllum called Tamanu. French researchers in the 1930's became interested in the oil for its wound healing properties. There are several documented cases in the medical literature of the time, illustrating that this oil has therapeutic uses in cases of severe skin conditions.

Case Studies. A 57-year old woman was admitted to a hospital in Paris with a large, gangrenous ulcer on her leg that would not heal. Normally, the leg would have been amputated. The leg was treated regularly with dressings of Calophyllum, and healing took place slowly within 7 months. The wound healed completely leaving only a smooth, flat scar.

The oil was used to treat a young teenage girl whose leg had been crushed 4 years before by a cart with iron wheels and on whom grafts had failed. New grafts were attempted and after a treatment for 10 days with Calophyllum oil the 12 grafts worked perfectly, the wounds closed and the girl was cured within 2 months after admission. In 1934 Calophyllum was prepared with ethyl ether and injected to treat leprous neuritis. Since this time, the oil of the seeds was tested on various skin problems and disorders.

Burns treated with Calophyllum have showed good results. Burns cured include: burns to the face from phosphorus; burns to the head from a pot of boiling milk; burns to the hands from a batch of caustic soda; burns to the scalp from boiling water and burns to the poplitaeal area (back of the knee) from inflammable oil.

Modern Uses. In its native habitat, both plant and oil have been used medicinally to treat a variety of ailments, mostly skin related. This oil can be used on either mucosa or epidermal lesions. It has been effectively used to cure chapped feet and hands, chilblain and skin cracks, vaginitis, erosions and ulceration of the cervical matrix, breast cracks, bites, stings, acne and acne scars, diabetic sores, herpes lesions, and anal fissures. It has also been used for hair and scalp conditions, eczema, psoriasis and facial neuralgia. Oil of Tamanu has an amazing capacity to accelerate wound healing and the growth of new tissue, a process called cicatrization. The unique cicatrizant properties and the anti-neuralgic effect of Calophyllum are not as yet explained by current scientific literature. Another principle use of the oil is for radio-dermatitis and has been used by dressings to heal lesions from X-ray therapy. Before surgical treatment, the oil has been applied to recent anal fissures with success. Post-surgical treatments brought about sedation of pain and resorption of tissue on treatment after breast surgery, crushing of the leg, and two thigh amputations in which the femurs were visible over a length of 4 cm. The healing of varicose ulcerous wounds, leprous wounds, especially when the wound is infected or becomes eczematous are considerably slower and the wounds must first be treated with medicine such as Hexomedine or Neomycin compresses. Calophyllum is used as a treatment for various problems of the hair and scalp, for eczema, psoriasis and facial neuralgia as well. The essential oil of Ravensara and the vegetable oil of Calophyllum have been studied together by Dr. D. PenoŽl and mentioned in Phytomedicine, 1981 as a treatment for shingles (zona) and has been shown to have pronounced amelioration of the problem.

The oil of Calophyllum easily saponifies and produces an abundant lather on contact with sea water.
