Coleus Forskohlii: Benefits and Uses


Coleus forskohlii is a small perennial plant in the Lamiaceae, or mint, family. Originating in India, Coleus forskohlii has been used in traditional healing modalities for centuries. The tuberous roots of Coleus forskohlii are often pickled and eaten.

The roots contain an active ingredient called forskolin. Forskolin is a type of labdane diterpenoid, compounds known for their antimicrobial and anti-inflammatory properties. Coleus forskohlii has historical applications in medicine for heart disease, respiratory disorders, abdominal colic, convulsions, and insomnia. [4, 5]

Coleus forskohlii, Forskolin & cAMP

Forskolin activates adenylate cyclase, an enzyme with important functions in nearly all cells of the human body. Adenylate cyclase creates cyclic adenosine monophosphate (cAMP) from adenosine triphosphate (ATP), leading to increased intracellular cAMP levels. [1, 5, 8]

cAMP acts as a second messenger to aid in intracellular signal transduction. cAMP is a catalyst for many hormones, including hormones of the HPA-T axis. [5]

cAMP stimulation by forskolin has been found to reduce inflammation, relax smooth muscle, lower blood pressure, and prevent platelet aggregation. cAMP also has important roles in modulating bronchodilation, and is a positive inotropic agent. [5, 7]

Antioxidant and Anti-inflammatory Action

Forskolin’s antioxidant and anti-inflammatory action is due to the inhibition of macrophage activation, followed by a decrease in thromboxane B2 and superoxide levels. Some studies have found forskolin to be beneficial in cases of asthma, heart disease, hypertension, and diabetes. [RR1] Forskolin’s antioxidant properties have been shown to be similar to the effects of vitamin E. [7]

Cell Growth

cAMP signaling is also associated with cell activities. These include preventing cell growth and migration  and stimulating mesenchymal-to-epithelial transition. [8]

Body Composition and Diabetes

Forskolin may offer benefits to body composition. Research has shown that by increasing cAMP levels, forskolin can increase lipolysis and inhibit weight gain in rats fed a high fat diet. [3] cAMP may also play a role in maintaining and increasing lean body mass. cAMP’s action in hormone regulation may increase basic metabolic rate, regulate the body’s thermogenic response to food, and increase the use of body fat. [5]

Forskolin may be effective for maintaining health blood sugar levels. Forskolin, through elevating cAMP levels, has been found to enhance insulin release by glucose. This occurs by cAMP activating two major beta cell signaling pathways. One study found chronic administration of forskolin lowered fasting glucose serum levels in healthy rats and reduced fasting hyperglycemia severity in diabetic rats. However, more research is needed to determine dosage protocol for a human population. [7]


serotonin, melatonin synthesiscAMP is also an essential element in making melatonin. The melatonin synthesis pathway begins with tryptophan. Tryptophan is converted to 5-HTP by the enzyme tryptophan hydroxylase (TPH). Then, aromatic amino acid decarboxylase (AADC) forms serotonin from 5-HTP. Serotonin requires N-acetyltransferase (NAT) to produce N-acetylserotonin (NAS). Finally, hydroxyindole-O-methyltransferase (HIOMT) makes NAS into melatonin. [2, 6, 9]

cAMP can increase NAT transcription and activity, leading to increased melatonin synthesis. Additionally, the enzyme TPH is phosphorylated by protein kinase (PKA), which is dependent on cAMP. Heightened cAMP signaling may stimulate serotonin production through increasing TPH protein synthesis or by stabilizing TPH protein levels. Thus, more serotonin is available for the pathway to synthesize melatonin. [2, 6, 9]


ForsLean®- A Source of Forskolin

Sanesco’s Targeted Nutritional Therapy™ (TNT) formula SomniTR™ is designed to promote health sleep. This formula supports optimal melatonin production by supplementing multiple steps in the serotonin-to-melatonin pathway and also influences inhibitory GABAergic activity.* One of the ways it supports melatonin is with the inclusion of ForsLean, a branded form of Coleus forskohlii standardized to 20% forskolin.

“Educating Sanesco’s clients is the culmination of a life’s work.” Beginning when she left the hospital environment to manage a functional laboratory, Genova Diagnostics (formerly Great Smokies Laboratories) in 1987, Dr. Connie Shoemaker has continued to increase her knowledge of herbs and biochemistry as a journey of love. With her bachelor’s in science from Western Carolina University, she had worked in hospital laboratories for the first twelve years of her career. Then, personal health challenges led her to discover a new approach to her health and a determination to share it with others. In 1991, she began teaching and educating innovative practitioners in the U.S. and internationally as a manager of marketing, sales, and customer service.

The addition of her Doctor of Naturopathy degree to her existing knowledge base expanded her knowledge and her respect for a more natural approach to healing through balance. At Sanesco, she initially served to oversee technical development of products and services.

Now, she educates Sanesco’s clients on application of the CSM™ model for their specific patients and how to integrate the CSM™ model with other modalities they offer in their practice. In her personal life, Connie educates private clients on various health topics.
