Mastic gum for jawlines? The truth is far simpler.

Mastic Gum Overview

Stay with me and you'll learn how to spot real mastic and a simple trick that makes grinding it a breeze in your kitchen.

What is Mastagi?

Mastagi, also called mastic gum, comes from the tiny tear-shaped resin of the Pistacia lentiscus tree that only thrives on Greece’s Chios island, where the resin is harvested and dried by hand. The tree’s bark is cut in summer, the sap drips onto the ground and hardens into the characteristic tears that are later washed and sorted.

Traditional uses

Traditionally Unani healers classified mastagi as hot and dry, using it to settle wind, calm nausea and support the stomach. People chewed a small tear after a heavy meal, added a pinch to honeyed milk, or mixed it into a jawarish paste. Because the resin is very hard, you should only chew a small piece and avoid it if you have dental work or a cracked filling.

Korean trial length

A Korean study ran for six months, having participants chew mastic daily, and found no visible change in jawline shape.

Jawline claim myth

The jawline hype claims that hard mastic will sculpt a sharper chin, but chewing only thickens the masseter muscle a little. No bone reshaping occurs, and over-chewing can irritate the TMJ, causing clicks or pain. A six-month Korean trial with regular chewing showed no measurable jawline improvement, confirming the lack of scientific support.

Real vs fake mastic

To tell real from fake, hold a tear between thumb and finger for a minute; genuine mastic turns tacky and smells clean. Bite it, it softens after thirty seconds. Real Chios tears are pale, almost white and translucent, unlike deep yellow impostors. You can also check the price: authentic Chios mastic is one of the most expensive food resins, so unusually cheap packages are likely fake.

The one tip to remember

The one practical tip: freeze the mastic tears for about ten minutes before grinding. The cold makes them snap into a fine powder, while room-temperature pieces tend to clump and are harder to crush. After grinding, sift the powder through a fine sieve to remove any larger shards before adding it to recipes.
