Scientific Name: Biancaea sappan
Sappanwood, also known as Caesalpinia sappan, is a flowering tree that is native to Southeast Asia, including Indonesia, Malaysia, and the Philippines. It is also found in parts of South Asia and the Pacific Islands.
Sappanwood produces a red dye that is obtained from the heartwood of the tree. The dye, which is often called "Brazilwood" or "Sappanwood red," has been used for centuries as a natural colorant for textiles, leather, and other materials. It produces a range of shades of red, from pinkish-red to deep maroon.
In addition to its use as a dye, sappanwood has been used in traditional medicine for various purposes. It is believed to have anti-inflammatory, antimicrobial, and antioxidant properties, and has been used to treat conditions such as traumatic injuries, amenorrhea, dysmenorrhea and abdominal pain.
Sappanwood is also valued for its ornamental value and is sometimes grown as a garden plant. It is a relatively small tree, growing up to 6 meters tall, with compound leaves and yellow flowers that bloom in the spring.
