The smell.  I read online that neem oil smells like peanuts and garlic, but I thought I'd give it a try anyway after reading about it's amazing healing properties.  But the smell is too much for me.  If you have chronic skin conditions, then go ahead and get it.  But if not, probably try argan oil instead. 

I bought another organic brand for 1/2 oz at $12.  Tried this to save a few dollars.  It is the same as far as I can tell.  I used it on a skin condition and it worked the same as the other Neem Oil brand.  It has proven useful on my dtr's psoriasis, a skin wound, and on a dry itchy psoriasis scalp condition.  Yes, it smells like old onions but it works.  I tried mixing it 50-50 w organic tumeric oil and that seemed to reduce the odor by about 80% to where it was tolerable.
