Black seed oil is known for its anti-inflammatory, anti-fungal and anti-bacterial properties. It works well as an ingredient in toothpaste as it cleans the bad bacteria out of your mouth and protects your teeth and gums. This toothpaste also contains turmeric and oregano oil, both of which have the same anti-bacterial properties. The addition of orange peel and lemon grass cleans your teeth and gums and gives the toothpaste a fresh flavor. Goldenseal is another essential ingredient in the toothpaste that has antimicrobial and antibacterial properties and also soothes inflamed gums.
