Black Seed contains fixed oils (palmitic, stearic, and oleic acids), proteins, alkaloids (compounds with antibacterial, anticancer, and other properties), saponins (with anti-carcinogenic, anti-microbial, and anti-inflammatory, properties) and volatile oil (essential oil). The most thrilling compound in Black Seed is thymoquinone or TQ for short. It has been studied and shows a lot of potentials to enhance anti-cancer drugs. It is natural. It is non-toxic to healthy cells and can be ingested by humans and easily absorbed. We are not medical professionals and are not advertising the use of Black Seed Oil internally, but we would love to tell you all we can gather about this incredible natural ingredient. At Katari Beauty, we are only promoting Black Seed for its properties related to clear and healthy skin.
