The trichomes are sticky and their sprouts form a protective layering that prevents offensive insects from reaching the surface of the plant. The chemicals within the trichomes also make the cannabis undesirable for hungry animals to devour. The resin helps to insulate the plant from weathers containing high winds and low humidity. Additionally it creates a natural ‘sun-screen’ that protects the plant against UV-B rays.
Historically man has used the cannabis plant for its medicinal properties. The euphoric properties too have coveted its influence with growers favouring strains with higher THC concentrations. The trichomes house much more than just THC, come to find out years later. Not only do the trichomes house all the medicinally available cannabinoids of the plant, but comes the discovery our human physiology and the existence of our very own ‘in-house’ Endocannabinoid System. Equipped with receptors specific to Cannabinoid messages of healing and relief, the Cannabis Plant deserves further study, resourcing to the ill and respect as a medicine.
Trichome -(Greek) Definition: ‘Growth of Hair’
Location of the major cannabinoids responsible for the medical distinction of,… cannabis.
- Sticky resinous growths
- Trichomes house the active medicinal ingredients of cannabis
- Trichomes evolved as a defence mechanism of the cannabis plant -much like an evolutionary shield
- This protective layer prevents insects infiltrating, animals devouring, and weather damaging the cannabis plant.
Trichomes are the sticky resinous growths which are home to the active medicinal ingredients in cannabis.
There are 3 main types of trichomes on a cannabis plant.
- The smallest of the three coming in at 15-30 micrometers
- The head cells secrete a resin alongside an accumulation of related compounds
- When the gland matures, a protrusion may form from the pressure of accumulating resin.
- Larger in size, measuring approx 25 to 100 micrometers
- More numerous in count
- Globular-shaped head
- The head typically has 8 – 16 cells, that form a convex rosette which secrete cannabinoids and related compounds
- There are an abundance of Cannabinoids in the capitate-stalked glands
- During flowering, the capitate glands that appear on the newly formed plant parts take on a third form. Some of the glands are raised to a height of 150 to 500 micrometres when their stalks elongate.
- These glands appear during flowering forming their densest cover on the female flower bracts
- High concentrations are also on the small leaves that accompany the flowers.
- The male flowers have some stalked glands, but they are smaller and less concentrated than on the female.
