"Ok, let me tell ya' this stuff is POTENT! I am not kidding here. Do NOT drop this bottle, which I have not done yet, but am very very clumsy most of the time, so am a bit nervous handling this teeny bottle. Yes, it is a very small bottle, but you only need a drop. One drop is like the juice of an entire onion. It is like magic! How do they do that anyway? I bought this because I am getting some grey hair and I read that you can put this on your scalp because onion has enzyme catalase and has been used for centuries as a topical treatment and home remedy for grey hair. I don't know if it will help with grey hair yet, because I have only been using it for a couple of weeks. I mix this with Castor Oil which is also suppose to help with grey or thinning hair and hair health and grape seed oil. I put 3 drops of this in a quarter cup and it was MORE than enough. I have it in an eye dropper; REALLY need to get a plastic bottle applicator, and will this week. I put it on my scalp and scrub it in and then put a shower cap on for 20 minutes and then shower it out. I tell you my hair looks and feels great. Like I said, not sure about the grey yet, but hubby says my hair is darker and looks like I just colored it. I think it looks darker because it is shinier. Love it!" - P. Williams

"I am not sure how many onions they put in that small bottle, but be careful because it is very strong....I love it, and I thought the bottle would have been too small, but when I open it, I realize that I have supply for more than a year! I strongly advize you to try it!!!" - Midsie

"Great! I will order again." - L.A.

''This is exactly what I needed.  We are using this for training a service dog.  I just wish that it came with a warning.  This stuff was so potent that I had to open it outside.  I double bagged it once it was open, and placed it in the garage.'' - C. Erdos
