R'ntz

(Zk'ttles x Gelato)

Bred by Cookies from a cross of Zk’ttles and a Gelato #33 phenotype, this one changed the game and has since gone on to produce numerous other phenotypes and offspring, some of which have joined it in our regular rotation (Après, Rose Gold R’ntz, Sunset R’ntz, Lemon Cherry Gelato [probably]). A proper cut of R’ntz exhibits wispy, electric lime-green buds with royal purple spots under a sugary layer of trichomes, and ours is the real deal. R’ntz exhibits aromas of sweet, sugary fruit that are offset by mild undertones of fresh earth and pine. Unlike many other candy cultivars, these aromas translate brilliantly to the strain’s flavor and helped solidify its place as an instant classic.

Limonene

Limonene is a terpene commonly found in the peels of citrus fruits like lemons, limes, and oranges, as well as in cannabis flowers, spruce trees, and other plants. It is commonly used in foods, beverages, fragrances, cleaners, and cosmetics due to its pungent sweet citrusy aroma. It has been identified in peer-reviewed research as inducing anti-stress[1], anti-anxiety,[2] anti-depressant,[3] and anti-inflammatory (in the airways)[4]^,[5] effects in mouse models. It has also been identified as having antioxidant[6] and anti-cancer[7] properties in human trials and has been identified as a potential muscle relaxant[8] and relaxation aid[9].

Myrcene

As one of the most common terpenes present in the cannabis plant, abundant levels of myrcene can be found in cultivars from around the world. Often used as an additive in food manufacturing, myrcene can be found naturally in mangos, lemongrass, and bay leaves. Various studies on animal models have shown some promising applications for this terpene, including sedation[1], muscle relaxation[2], anti-inflammation[3], and overall pain relief[4]. Analyses of essential oils high in myrcene content have also indicated the possible antioxidant[5] and anti-ulcer[6] properties of this terpene. Furthermore, research on mouse models has demonstrated the potential of this terpene to treat ischemic stroke, due to its neuro[7] and cardiac[8] protective effects.

Linalool

Linalool is a naturally occurring terpene found most commonly in lavender and basil. Due to its sweet, floral aroma, it is often used as an additive in several household products like soap and perfume. Several animal studies have implicated this terpene in the potential treatment of various conditions, including depression[1], anxiety[2], stress[3], inflammation[4]^,[5], and pain[6]. In addition, animal models have demonstrated that linalool may possess anti-convulsant[7], anti-asthma[8], and sedative[9] properties. Human trials have even linked the usage of linalool-rich essential oils to menstrual pain relief[10].

Caryophyllene

Caryophyllene (also known as β-Caryophyllene or BCP) is a terpene found in several common herbs and spices like cloves, black pepper, cinnamon, basil, and oregano. In cannabis, caryophyllene often contributes to a peppery, earthy flavor profile. Animal models have demonstrated a possible interaction of caryophyllene with the endocannabinoid system[1] as well as pain relief via CB2 activation[2]. Other animal studies have identified this terpene as a potential treatment for several conditions, including anxiety[3], depression[4], inflammation[5], and overall pain relief[6]. In addition, in vitro studies have evaluated the antioxidant[7] and sedative[8] effects of this terpene. Finally—and perhaps most noteworthy—both in vitro[9] and animal[10] studies have implicated caryophyllene as a potential treatment for cancer, with human trials demonstrating its potential to treat nausea[11].

Pinene

Pinene is unique in that it has two main isomers, alpha and beta, that are both common in the cannabis plant. These isomers have the same molecular composition but different arrangements and are usually notated as α-pinene and β-pinene. As its name suggests, this terpene has a piney aroma and is abundant in most conifers. Pinene can be found in a large variety of plants, including rosemary, parsley, dill and—not surprisingly—pine trees! Various animal studies have demonstrated that pinene may exhibit gastroprotective[1], anxiolytic[2], and anticonvulsant[3] properties, as well as the potential to improve sleep quality[4]. In addition, some animal and in vitro studies have implicated this terpene as a potential treatment for various neurodegenerative diseases[5], including Alzheimer’s[6] and Parkinson’s Disease[7], due to its neuroprotective properties[8]. In vitro research, including studies on essential oils rich in pinene, has shown that pinene may display antioxidant[9], anti-inflammatory[10], and antimicrobial[11] effects. Finally, as with several other terpenes, pinene has been linked to anti-tumor[12] and anti-cancer[13] activity.
