i was sick once in indonesia and went to a local healer, she has stingless bees, and some made sour honey from flowers from a specific tree, i forgot which tree tho. she said the sour honey is good for people with high sugar level and stops insects attacking you.
ive also heard about native stingless bees in mexico.
i think native bees are extremely important because they are necessarily for pollination unlike hybrid conventional honey bees which disrupt local biodiversity
