While in Phra Khanong market, the only Burmese market I know of in Bangkok, I bought the following seemingly-to-me similar products: brown to black dried tea leaves (pictured below).
I drank a small glass of hot tea made from these leaves, and it had a very mild and comforting taste.
What is this Burmese/Myanmmarese brown-to-black dried tea leaf? br/> What is the English name, please?
