It is the main way old people here make their oils, so I got inspired by them :)
I guess not the best way for all herbs, but the lemon balm oil turned out to be quite effective when I tested it to insect bites, so I would say that it worked well :)
I adore melissa but have rarely seen it here in Asia.
You have all the tropical treasures there, let us have the melissa, haha!
But seriously, I don't see any reason why you can't cultivate it there, right? I hope you can find some!
Thank you so much for your encouraging feedback!
