I have done extensive research on Essential Oils. I have purchased them at various stores, websites, and through Tiki. My lungs are sensitive to certain fragrances and ingredients so I must be careful which oils I purchase. Haku Farm, thus far have been the best. I use them in my Aromaglobe's, spray a fine mist on my bed linens and drapery and even use some on my skin. I trust this product and would highly recommend. Lemongrass is one of my favorites.
