How can you use kalonji as a treatment of acne?

Kalonji, or black seed (Nigella sativa), is known for its anti-inflammatory and antimicrobial properties, which can help in treating acne. You can apply kalonji oil directly to the affected areas or mix it with a carrier oil for a more diluted application. Additionally, consuming kalonji seeds or oil may promote overall skin health from within. However, it's advisable to perform a patch test first to check for any allergic reactions.
