Unlocking the Secrets of the King of Spices: Exploring Its Chemistry, Health Benefits, and Medicinal Wonders

Abstract

Black pepper, the “King of Spices”, has a rich history of culinary and medicinal uses. This versatile spice contains multiple bioactive compounds, such as alkaloids, essential oils, flavonoids, and lignans, which has been studied extensively for its health benefits, including antioxidant, anti-inflammatory, antimicrobial, and gastroprotective properties. Piperine, an active alkaloid of black pepper, enhances the bioavailability of nutrients and drugs, making it a valuable adjunct in pharmacology and nutrition. However, high doses of piperine may lead to adverse effects, including gastrointestinal irritation, hepatotoxicity, and interference with drug metabolism. This chapter provides a more detailed comprehensive review to completely understand pepper’s therapeutic potential and safety profile. © 2026 selection and editorial matter, Pankaj Kumar Chaurasia, Shashi Lata Bharati, Sunita Singh, and Ashutosh Mani; individual chapters, the contributors.
