This is genuine Tibetan herbal incense made by located in Nepal factory "Himalayan Medicine Industries". This is the manufacturer mostly making high quality Tibetan Herbal Medicine products. These incenses have the same quality as their herbal mixes.
This incense is especially dedicated as an offering to Green Zambala and comes in powder form, which generally called "sang" (Tib. བསང་, Wylie: bsang). The practice of burning of these incenses is called as "sang offering" (Tib.: བསང་མཆོད་, Wylie: bsang mchod).
