The first widely used leprosy treatment came from an old Indian remedy. Who deserves the credit?

Indian claim
Oil from the seeds of the chaulmoogra tree (Hydnocarpus) was used against leprosy in traditional Indian medicine long before Western doctors adopted it in the 19th century.
Evidence for the Indian claim
- Chaulmoogra is recorded as a folk remedy in India and Southeast Asia, and British doctors in India used it from the 19th century.
- In recent decades India also produced the Mycobacterium indicus pranii (MIP) leprosy vaccine, developed by G.P. Talwar's team and approved by the Drug Controller General of India and the US FDA.
Commonly credited to
Raw oil was hard to swallow and too thick to inject. In 1915–16 Alice Ball, an African-American chemist in Hawaii, made an injectable form (ethyl esters), the 'Ball method', which became the main leprosy treatment until sulfone drugs in the 1940s.
Evidence for the other claim
- Ball's chemical work made the remedy usable on a large scale; it is properly hers, although for years it was credited to Arthur Dean.
- The cure for leprosy today is multidrug therapy, recommended by the WHO in 1981.
What historians and scientists say
Chaulmoogra came from Asian, including Indian, traditional medicine, and was turned into an effective injectable drug in Hawaii. It is a fair example of a traditional remedy developed further elsewhere.
