Home » Terpenoids And Cannabis Strains

Beyond sativa and indica, iStrainGuide(iSG) anchors a reliable method of cannabis identification on the unique study of terpenoids. Our mission is to inform patients - and the general public - about cannabis, and its value to society as an effective medical solution. iStrainGuide is intent on teaching patients how to match strains to their medical symptom(s). To accomplish this task, we have constructed iStrainGuide’s Cannabis Index, an ever-expanding compendium of cannabis strains designed to list the following per entry:


- Description of the strain’s appearance and aroma

- Medicinal Values extrapolated via the aromatic terpene.

- Genetic Lineage of any known parental phenotypes.

- High-Resolution Image of an exceptional sample.

- (I)ndica or (S)ativa Indicator; w/ hybrids as (dominant/rec.)

- Dispensary Logo to identify strain’s local availability*


This application also incorporates a live feed of iStrainGuide’s Twitter account @istrainguide: a continuous broadcast of historical, medicinal, social, and spiritual facts promoting cannabis as a beneficial medicine, fiber, and religious sacrament.

We Hope You Enjoy iSG, and
Thank You for Downloading



Basic Terpene Chart

Similiar to basil, lemon grass, or peppermint, cannabis emanates its own unique fragrance, consisting of hydrocarbons found in the plant's resin. These hydrocarbons are a group of compounds known as terpenoids. They offer a unique and efficient way of anticipating how a strain will affect a patient, because of how they intereact with active cannabinoids like tetrahyrocannabinol (THC). Use this Basic Terpenoid Chart to familiarize yourself with the fragrances of those terpenes most often found in medicinal cannabis.


citrus, clove, earthy, fruity, green, vegetative, mango


citrus (orange, tangerine, lemon, and grapefruit), Rosemary, juniper, peppermint


spicy, sweet, woody, clove, camphor, pepper
Pinene: alpha: pine needles, rosemary

Terpineol: floral; lilac, citrus, apple/ orange blossoms, lime
Borneol: menthol, camphor, pine, woody
Delta 3-Carene: sweet, pine, cedar, woodsy, rosemary
Linalool: floral (spring flowers), lilly, citrus and candied spice.

Nerolidol woody (like fresh tree bark), floral, green, waxy, citrus
Humulene vietnamese coriander, hops, woody, clove

In the field of aromatherapy, terpenoids have been administered for their therapeutic value. Recent findings have concluded that terpenoids actually change how the body metabolizes cannabinoids like tetrahydrocannabinol (THC). Understanding how to properly identify a terpenoid will enhance your knowledge of cannabis, and enable you to select a strain based on what it is intended to treat.
