Black pepper – Properties and Medicinal uses


Black pepper, peppercorn, or Piper nigrum, is a medicinal plant belonging to the family Piperaceae. It has been used for decades in treating cold and flu, and improving digestion. It is commonly referred to as the “king of spice” due to its popularity. Native to India, but now found and grown in tropical regions of the world, thanks to the Indian and Arab traders who help spread it.

It is important to note that peppercorns may vary in color, depending on the maturity of the fruit before harvest and method of processing it is subjected to. Black peppercorns are derived from the dried unripe fruit which are usually left to shrivel and turn black under the sun. The green peppercorns are the dried unripe fruits, and are plucked while the berries are still unripe and green. The white peppercorns however, are the matured and ripe berries of Piper nigrum.


Dried powdered pepper has been used since the ancient past both as a flavor and a medicine. Being the world’s most traded spice, it is the most common spice added to dishes all over the world. The spiciness of black peppercorn is due to the compound piperine, and not capsaicin, which is characteristic to the chilli pepper.
