More about Cymene

Cymene is a terpene that is commonly found in both cumin and thyme. 

p-Cymene is an alkyl aromatic hydrocarbon mainly used to study oxidation reactions under various conditions to synthesize highly valuable intermediates and building-blocks.

The monoterpene’s short half-life is a limitation for several approaches that have been used to improve pharmaceutical properties of the compound.


Cymene’s antimicrobial properties make it useful for topical creams, and found to have immunoprotective properties. 

Cymene appears to be a particularly powerful antimicrobial as it serves a dual purpose. It is one of many antimicrobial other terpenes, additionally, it works synergistically with these other terpenes to produce stronger results.

Cymene  has been widely investigated due to the urgent need for new substances with antimicrobial properties, to be used to treat communicable diseases whose diffusion in developed countries has been facilitated by globalization and the evolution of antimicrobial resistance. 


Cymene has anti-fungal properties.

p-Cymene possessed lower antifungal activity than carvacrol and thymol,  but works synergistically with other terpenes to create a stronger protective influence against skin infections and fungal growths.


Anxiety Stress and anxiety are common and complicated conditions affecting people of all walks of life.  Terpenes like Cymene help regulate mood through several mechanisms.


There is evidence to suggest that P-cymene has analgesic properties. It can be difficult to determine exactly what is impacting on the nervous system with essential oils, given the complexity and the variety of terpenes that are found in any one oil, however, p-cymene combined with the other terpenes that are found in sweet marjoram oil clearly has beneficial effects for numbing and soothing pain.

Antioxidant Potential

Cymene may present a new strategy in the development of treatment for many diseases in which oxidative stress plays an important pathophysiological role.

Memory Enhancer

Cymene can help to inhibit the action of AchE, which means that the neurotransmitter Acetylcholine has a longer duration. A mechanism that can help improve memory, attention, and motivation. Taken in excessively, AchE inhibitors can cause problems, however, the benefits of microdosing is shown helpful for attention disorders, Nervousness, and mood alterations.

Medicinal Potential 

While it is obvious that cymene has powerful medicinal effects, more research is needed to determine its mechanisms of action as well as its potential in developing new delivery mechanisms.

Commercial Interest 

The antimicrobial and antifungal features are of particularly special interest to the commercial packaging industry. The idea of edible films is not new. The wax coatings that are added to fruits and vegetables have been around for over 100 years. The idea of using edible films that are functional in other ways, such as blocking light, or medication, is a relatively new thing. 

There are some considerations being given to active biomolecules which can act as a biodegradable, non-toxic, antimicrobial penetrating agents. 

One new film is chitosan, which is safe and quite useful in and of itself, but has still suffered from some issues in terms of water permeability that lower its effectiveness. Oregano essential oil is being added to chitosan to make a powerful antifungal and antimicrobial wrap. The active ingredient in oregano essential oil is p-cymene, along with other agents such as carvacrol and thymol.
