I have tried numerous 'fungal nail' treatments as I have had a problem for well over 20 years and nothing worked. The nails on both my big toes were actually black and growing twisted. A friend gave me my first bottle of this oil and within 2 months what a difference. I am now ordering my 3rd bottle and my nails are almost back to normal. The black has gone and the nails have straightened - still a bit thicker than they should be and not as clear as they should be hence ordering another bottle. It is magic. Thank you.
