Excellent oils, amazing service, will supply samples for the cost of postage only, so you can try before. You buy. After receiving samples I have bought oils and balm several times. The balm helps my elderly mum who suffers with pain from osteoporosis. White and red oils brilliant for sleep. I usually use the White, but occasionally when rest is needed, I take the red. I also use the oils with my little dog, who had cancer treatment last year. and have used the White oil to calm 3 dogs on bonfire night noise from fireworks and again for the noise of fireworks at new year. They had 2 drops each and were nice and relaxed, usually they would be very anxious. Blue livens you up, I have just had samples of green and purple, so yet to try them, but I expect them to be as good as the others.
