  1. If you wish to include references in Caraka, some are Su 2.25, Su 25, Su 27.16–18, Ci 20.26–33, and Ci 26.52–65. I’m unsure if you are tracking anti-HIV activity of various foods and herbs. For gaveduka, one is Screening of traditional medicines for their inhibitory activity against HIV-1 protease. As bacteria and viruses such as tb, malaria, zika, ebola, dengue, and HIV are becoming more pervasive, and many foods and herbs have various antibiotic and antiviral properties, perhaps worth doing.

  2. As you know, it is widely grown in east Asia and easily found from such sources. Is there any Indian variety commercially grown and available?
