Cannabis can easily be identified by its unique fragrance — but what gives cannabis its distinct odour? Terpenes! One of the many compounds found in the cannabis plant, terpenes give different strains of cannabis their own scent.
Terpenes have a multitude of health and medicinal benefits. Many physical health conditions and mental health challenges can be alleviated with the help of terpenes.
What are Terpenes?
Terpenes are a type of compound found in the cannabis plant. Specifically, terpenes are found in the trichomes of the plant. There are more than 150 kinds of terpenes in cannabis. Some are found in minute quantities, while others are more prevalent.
Terpenes are what give cannabis its unique odour. They also contribute to the flavour and colour of cannabis. How much terpene is in a plant is impacted by temperature, light exposure, and when it is harvested. Typically the more fragrant cannabis is, the higher the terpene content.
What are the Effects of Cannabis Terpenes?
Terpenes interact with other cannabis compounds, creating what is called the entourage effect. The impact of any compound, including terpenes and cannabinoids, is greater when it is consumed with another compound. They work together and exaggerate the effects of each other.
Research into terpenes’ effects is still in the early stages, but scientists are discovering that terpenes have many medicinal benefits.
Some terpenes, such as humulene and linalool, act as analgesics, providing pain relief to the person using them. Terpenes like camphor and carvone have antiviral properties, while menthol and terpinolene are antimicrobial.
Certain terpenes even seem to boost mood. Linalool and pinene have been shown to have antidepressant effects. Other terpenes like limonene and myrcene are being studied in cancer research. They show an ability to slow down the growth of cancer cells and tumours.
