Sumba is an east-Indonesian island, located south-east of Bali. It is an island clothed in mystery, and known for centuries as the Sandalwood Island. Sandalwood was the only known cure for many diseases until penicillin was invented. The Sumbanese traded with the Chinese until the 16th century, after which the Arabs became the most important trading partner until the early 20th century. More Sumba from East Sumba .com
