If you follow the instructions properly, I had antifreeze leaking from my head gasket and it fixed it immediately. I couldn't drive on the freeway (I purchased the car like that) and have been able to drive it o the freeway for hours with no problems.

And to think that I thought there was only just lavender out there well that and french lavender well jokes on me cause Pure Body Naturals knows what they are doing with these oils Kashmir Lavender is simply divine, believe me on this one. I make a rub for my grand daughter and it calls for essential oil Lavender for its relaxing and calming properties but now that I have this Kashmir lavender what a difference it has made it is still lavender but the smell lasts longer and it seems to be more potent but that is not a bad thing and it isn't over the top either, just proves that a little dab will do you. This product comes in a dark brown bottle so as not to spoil, keeping away from heat and light, also came with a glass dropper packaged with a bubble wrap so protect from breakage. This Kashmir Lavender is by far the superior of any of the lavenders that I have used prior. I received this product at a reduced price in exchange for my honest unbiased opinion in this review.
