the juicy:
I read that plant oils like lavender and tea tree oil "have been associated" with man boobs. Now I don't fully understand what they are implying but I guess you can buy lavender based products to use, like lotions or something. Then, I also read about eating soy products, like soy milk, can trigger growth too.
I heard a bit of a follow up on the lavender oil thing,some time back. The one known case where it was significant, a mother was rubbing lavender oil into her son's skin every day, over large areas (I forget,maybe he had a skin condition?). Anyway, really big quantities and prepubescent so low hormone levels, and he had some breast development.
I think the others are similar. Yes they mimic female hormones, but unless exposed to extreme quantities and having low hormones, notapt to have a significant impact.
But if you have fun trying anyway, why not?
