The most expensive essential oil on roses is the world's most expensive essential oil and is called the "Queen of Essential Oils". Rose essential oil helps to improve digestive tract function, adjust female endocrine, nourish the uterus, relieve dysmenorrhea, improve sexual indifference and menopausal discomfort, and especially has a good beauty and skin care effect. It can nourish the inside and outside to dilute spots, promote the decomposition of melanin, improve dry skin, restore skin elasticity, and let women have fair, elastic and healthy skin. It is an aromatic essential oil suitable for women's health care. Rose essential oil is rich in vitamin C, carotene, vitamin B and vitamin K. Vitamin K can promote blood coagulation.
