General info
Caesalpinia sappan shares similarities with C. echinata, a species of Brazilian timber in the pea (Fabaceae) family. Portuguese explorers initially referred to the trees as pau-brasil - pau as Portuguese for "stick," metonymy for wood, and brasa for brasil, Portuguese for "ember" - for the deep red hue characteristic of the wood. Pau-brasil was also used to described the Asian sappanwood. And besides sharing in the common name brazilwood, C. echinata and C. sappan also share in some botanical features, chemical constituents, and functional uses of dye and wood.

Botany
Sapang is a small tree, 3 to 5 meters high, with scattered spines. Leaves are compound, up to 50 centimeters long. Pinnae are about 20, opposite, and 10 to 20 centimeters long. Leaflets are 20 to 30, obliquely oblong to oblong-rhomboid. Flowers are yellow, on terminal panicles, 2 to 2.5 centimeters in diameter with densely wooly filaments. Fruit is a hard, indehiscent, shiny pod, about 7 centimeters long, and 3.5 to 4 centimeters wide, with a hard recurved beak at the upper angle.

Distribution
- Locally abundant throughout the Philippines at low and medium altitudes in dry thickets, parang, etc.
- Introduced, and probably of prehistoric introduction.
- Also occurs in India through Burma, Thailand, Indo-
China, southern China to Malaysia.

Constituents
- Coloring matter of sappan wood appears to be identical to the brazilin obtained from brazilwood.
- Study yield a principle resembling haematein.
- Resinous extract yields a crystalline principle, which when fused with potash, yields resorcin.

Others
- Dye: Heartwood yields a valuable red crystalline dye, brazilin. Chiefly used as a dyewood, popular for coloring cotton, silk, and wool fabrics. Elsewhere, used for coloring leather, silk, batik, calico printing, furniture and handicrafts. Also used for coloring wines and meats. Considered safe for coloring food products and pharmaceuticals.
- Lambanog: In some parts of the Quezon province, a popular colorant for the coconut liquer, lambanog.
Also, strip of sappan wood used to test for purity of lambanog, imparting a yellow coloration.
- Wood: (1) Firewood: has an energy value of 25,000 kj/kg. (2) Source of commercial redwood or Brazilwood. (3) Carpentry. Used for inlaying work, cabinetry, and with its straight grains, of great value in making violin bows and walking sticks.

The Sapan Wood Test
In the Quezon area, rather than medicinal, sapang finds greater use as a test for the purity of lambanog. Sappan wood is known to produce a red dye. Studies have identified brazilin as the wood constituent responsible for the color.
The Traditional Rural Lithmus Test: In rural Quezon, the sapan wood has long been used for testing the purity of lambanog. A strip of sappan wood swirled in unadulterated lambanog will impart a yellow color. Above: (1) Gin, bright pink. (2) Vodka, reddish-brown. (3) Bating, the initial distillate in the lambanog process gives a reddish-orange color. (4) Coconut lambanog with the typical "true" unadulterated yellow coloration (5) Nipa or sasa lambanog with a lighter yellow, probably due to a lower "proof."

Results showed protosappanin A or cyclosporine significantly prolonged heart allograft survival (p<0.01), alleviated myocardial pathologic damages (p<0.01) and decreased CD4/CD8 ratio (p<0.05) and inhibited perforin and granzyme B mRNA expressions in graft (p<0.05). Findings suggest protosappanin A prolonged heart allograft survival by significantly attenuating acute rejection. (58)
• Protosappanin A / Immunosuppression in Organ Transplantation: Protosappanin A from C. sappan has exhibited anti-rejection activity in heart transplanted rat. In the study, protosappanin A exhibited inhibitory effect on cell proliferation. It may act on T cells through inhibition of NF-kB activation and downstream gene expressions in IFN-r and IP10, while reducing T cell proliferation to induce an immunosuppressive effect. Results suggest potential therapeutic evaluation of protosappanin A for clinical organ transplantation or other T cell-mediated immune disorders. (59)
