Kigelia: Hormone-like Action.

Kigelia is an african tree, whose fruit is used to heal multiple health conditions thanks to its anti-inflammatory properties: rheumatism, snake bites, syphilis, but it's also used by african women in their beauty routine for keeping their breasts firm, since it contains flavonoids which stimulate micro-circulation.

Moreover it's been proven to be useful for treating wounds, eczema, psoriasis, acne and sun damaged skin. What a treasure, isn't it?

Not all that glitters is gold, by the way. So don't run to put your hands on this miraculous ingredient that will make your breast look brand-new and cure your acne and skin problems all in one.

The presence of steroidal saponins generate a hormone-like activity, which supports the dynamization of the skin. 
We are dealing then with a powerful substance that shouldn't be used lightly: you can't joke with the delicate balance of hormones in your body! On Aroma-Zone it says: 'not to be used in certain subjects'. What does it mean? When it comes to the maintenence of our health, they should be more specific. It might create severe hormonal imbalances in certain cases, so I would advise not to use this kind of actives without the supervision of your doctor. 
I'll take advantage of this post to remind you that natural doesn't necessarily mean safe. Natural substances can be extremely powerful, so don't ever underestimate their effects. Going natural has to be taken seriously, mainly when you decide to prepare your own cosmetics, always inquire about everything first, you don't wanna harm yourself because of your negligence! 
Sorry for my sermon, I just wanted to make sure you got the point! :)
