Oh!!! I didn't even know they're the same thing! I had been so crazy about this soap berry! but I did use this brand. https://www.treetotub.com/pages/soapberry like from head to toes and they even gave me a bag of the nuts that I can just put it with water then the foam comes out! Whoa!!!

The one you had in Thai called 'ma kham dee kwai' sounds intense that I didn't even think it's the same thing as soup berry (which sounds cute). New info!!! That's exciting lol
