Background Information on Onion Essential Oil

During historical times, onion was a very popular vegetable in ancient Egypt. A lot of money was spent on onions to feed builders of the Egyptian pyramids. In the later part of the middle ages onion (because of its strong smell) was used as a charm against the plague. The sulfur compounds in onions give them a sharp aroma and flavor, which made folk healers think they were indications that onion juice could prevent infection. Modern herbal practitioners believe that applications of onion will kill off warts and prevent acne.* They also recommend onion syrup as an expectorant. Onions are believed to be diuretic.* Onion oil is basically a superlative tonic, as it is rich in vitamins, including B2 (riboflavin), B1 (thiamine), and C.

Onion Essential Oil Reviews

“Fast shipping, very reliable. Good product as advertised” – BV

“The product order was very satisfactory.” – E. Gholar

“This is very powerful!” – H. Lima

“Love this product.” – H. Mudock

“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 advise you to try it!!!” – Midsie

”The item I ordered arrived promptly and with excellent warnings about the strong odor of the onion oil inside.”  – T. Muel

”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

”Oil is EXTREMELY potent. I got a strong whiff and it took my breath away.”  – E. Hicks

”So impressed with the quickness in which it arrived; I hit the send button and it was in my mailbox!!! THANK YOU!”  – C. Anderson
