Pink pepper (Pink peppercorn, aguaribay) is the berry of the plant Schinus molle which is born in Peru or from the plant Schinus terebinthifolius for which it is not a real pepper, but the fruit of the berries of these plants that are very beautiful aesthetically, but rather invasive as they can reach a height of 7 meters and a width of 10 meters.

It is also called:

• California Pepper Tree
• False pepper tree
• Peruvian pepper tree
• California Big Tree

Its essential oil contains antioxidants and antifungal components (1):

• β-pinene (25,23)
• epi-α-cadinol (21·29%)
• α-pinene (18·72%)
• myrcene (11·54%)
• sabinene (5·02%)

In another recent study, the essential oil obtained from the leaves of Schinus molle has a fairly similar composition, but, in this analysis, alpha-pinene, a terpene, is the main one with 23,49% . The action exerted by alpha-pinene has a cytotoxic activity against some types of immune cells (macrophages), only at high concentrations (2).
