Terpene Profile

Jack Herer

Jack Herer's unique effects, flavor, and aroma are heavily influenced by its terpene profile. Terpenes are organic compounds found in cannabis plants that contribute to their distinct characteristics.

  • Limonene: With a citrusy aroma reminiscent of lemon or orange peels, limonene has been associated with uplifting mood-enhancing effects as well as potential stress relief properties.
  • Caryophyllene: This spicy-scented terpene may offer pain-relieving benefits due to its ability to bind with CB2 receptors within our endocannabinoid system.
  • Myrcene: Often found in mangoes and lemongrass, myrcene has an earthy fragrance that contributes to Jack Herer's complex aroma. It is also thought to provide sedative-like qualities when present at higher concentrations.

These terpenes work together synergistically through what is known as the "entourage effect" - enhancing each other's individual properties while creating a more balanced experience for users. The combination of these specific terpenes helps define Jack Herer's invigorating cerebral high along with its soothing body relaxation effects without inducing overwhelming drowsiness or lethargy often associated with heavier indica strains.

Jack Herer is one of my all time favorites. Very nice day time smoke, and good for medical users as well. Smoke enough, and she'll sedate you just about enough, but in general very much an upper. So not a good strain if you want to fall asleep after smoking some. Jack Herer gives me enough energy to stay active and be a little buzzed while still doing my job for instance. She has a very tasty smell and smoke. Haze and Skunk mixed with a bit of freshness.

Sehr gut schmeckender Strain, mein "Batch" ist wohl etwas schwächer als Jack Herer üblicherweise, aber dennoch bin ich überzeugt, dass diese Sorte der Legende gerecht wird. :)
