Forskolin and blood pressure -
Food supplements containing forskolin together with homotaurine, L- carnosine , and folic acid reduced the fluid pressure inside the eye and improved eye nerve activity in a clinical trial on 22 people with glaucoma. Similarly, injections with the same compounds prevented nerve cell death in rats with injuries in the eye blood vessels [ 38 , 39 ].
All in all, limited evidence suggests that forskolin may reduce fluid eye pressure in people with glaucoma.
Oral forskolin was more effective than an asthma drug sodium cromoglycate and as effective as another one beclomethasone at preventing asthma attacks in two clinical trials on people with persistent asthma [ 40 , 41 ]. Injected colforsin daropate, a water-soluble forskolin derivative, prevented the tightening of the airways caused by a drug in a clinical trial on 36 healthy volunteers, suggesting its potential to prevent asthma attacks faster than oral forskolin [ 6 ].
Although the results are promising, only 3 small trials back the use of forskolin to prevent asthma attacks. More clinical trials on larger populations are required. Forskolin can increase blood flow by relaxing the muscles in the blood vessels. In a small trial on 21 elderly people, oral Coleus forskohlii extract lowered blood pressure through this mechanism [ 42 ].
In a small trial on 31 people with erectile dysfunction and a study in rabbits, injected forskolin improved the condition by increasing blood flow into the penis [ 43 ]. Both forskolin and its derivative NKH increased blood flow in animal studies [ 44 , 45 ].
Two small clinical trials and some animal research cannot be considered conclusive evidence that forskolin improves blood flow.
Further clinical research is needed to confirm these preliminary findings. In 3 small trials on 35 people undergoing heart bypass surgery, the water-soluble forskolin derivative colforsin daropate improved blood flow and reduced inflammation, thus reducing the likelihood of a poor outcome [ 46 , 47 , 48 ].
Similarly, it reduced airway tightening caused by tracheal intubation in 46 people. A forskolin derivative NKH was similarly effective in Guinea pigs when injected or inhaled before surgery [ 49 , 50 ].
Pretreatment of sheep before surgery with forskolin had similar effects. In addition, coating synthetic blood vessel grafts with forskolin prevented their rejection by the immune system [ 51 , 52 ]. Both forskolin and colforsin daropate improved blood flow into the kidney in dogs and rats, which prevents complications caused by both narcotics and drugs taken for heart failure [ 53 , 54 ].
Similarly, NKH reversed heart failure caused by narcotic drugs used in surgery, such as pentobarbital, propranolol or verapamil, in dogs [ 55 ]. Again, the evidence is insufficient to support the use of forskolin in the prevention of surgical complications.
Larger, more robust clinical trials are needed. No clinical evidence supports the use of forskolin for any of the conditions listed in this section. Below is a summary of the existing animal and cell-based research, which should guide further investigational efforts.
However, the studies listed should not be interpreted as supportive of any health benefit. Forskolin and C. forskohlii extract are often used for skin treatments, although they have only been tested in animal and cell-based studies. In mice deficient in the production of the protective pigment melanin, forskolin increased the production of the similar protein eumelanin.
This protected the mice against DNA damage and cancer [ 56 ]. Forskolin stimulated wound healing by promoting the migration of skin cells to the site of the wound [ 57 ].
Application of forskolin on artificial skin tissue repaired DNA damage caused by UV light and prevented skin cell death. Alternatively, it may protect by making the skin thicker and more resistant to this radiation [ 58 , 59 ].
Forskolin may also delay skin aging by reducing oxidative damage, as seen in animal and cell-based studies [ 60 ]. Comparison of cultured skin treatment with pure forskolin and C.
forskohlii extract showed that forskolin penetrated the skin faster when applied as plant extract, possibly due to synergistic effects with other compounds [ 61 ]. In heart tissue collected from people with irregular heart rate arrhythmia , forskolin relaxed the muscles and reduced arrhythmia [ 62 , 63 ].
The forskolin derivative NKH reversed damage to the heart in rats with chronic heart failure after a heart attack. In dogs, it prevented heart damage caused by sedative medication [ 64 , 55 ].
In heart cells, forskolin reversed some defects associated with a type of heart failure called mitral deficiency, which may improve outcomes after heart surgery for this condition [ 65 ].
Forskolin derivatives NKH77 and DMAPD increase the level of cAMP in heart cells better than forskolin itself, possibly making them more promising for heart therapy [ 55 ].
Forskolin may have some role in treating conditions associated with diabetes. As mentioned above, forskolin improves cellular insulin response. It also decreases blood sugar levels in rats [ 5 , 66 ]. Diabetic retinopathy is caused by high levels of sugar damaging eye vessels, which results in blood leaking into the eye and damaging vision.
Forskolin blocks two proteins responsible for glucose transport — GLUT1 and GLUT 4 , thus potentially helping to decrease blood sugar levels [ 67 , 68 ]. Forskolin, in combination with cilostamide, improved the development of human egg cells [ 69 ].
In rat egg cells, forskolin increased the rate of division and maturation [ 70 ]. In pig egg cells, forskolin delayed the development of egg cells and increased the production of the hormone progesterone [ 71 ].
Low forskolin doses increased testosterone and cAMP production by testes cells. However, these processes were blocked at high doses [ 72 , 10 ]. Also, forskolin increases cAMP buildup in the tail of sperm cells, making them more likely to fertilize an egg [ 73 ].
Keep in mind that the safety profile of forskolin is relatively unknown, given the lack of well-designed clinical studies. The list of side effects below is not a definite one, and you should consult your doctor about other potential side effects based on your health condition and possible drug or supplement interactions.
Mild adverse effects such as headache, low blood pressure, respiratory tract irritation, or stinging and blood vessel enlargement in the eyes are rare [ 74 , 75 ]. Coleus forskohlii extract caused liver toxicity in mice, especially when combined with diets rich in starch [ 76 , 77 ].
Because it increased the levels of cytochrome P in rats, forskolin may reduce the effectiveness of drugs broken down by this enzyme such as warfarin blood thinner and tolbutamide antidiabetic.
Ask your doctor about potential interactions of forskolin with any medication and supplements that you are taking [ 78 , 79 ]. Supplements are not regulated and their efficacy and safety are not supported by scientific evidence, so always speak with a healthcare practitioner prior to adding a product to your routine.
Manufacturers often label forskolin as a fat burner or appetite suppressant. However, these health claims are not backed by solid evidence, and you should not count on this supplement to help you lose weight. Instead, a combination of a balanced diet and exercise are the best way to lose weight.

However, the scientific evidence may not support the hype that surrounds this prominent weight loss supplement. Forskolin is a plant supplement derived from the root of a member of the mint family known as the Indian coleus that grows in Thailand, Nepal, and parts of India. While forskolin has long been used in folk medicine for asthma treatment and various other ailments, it is marketed nowadays, as a weight loss supplement.Video

In traditional Asian systems of medicine, it was used for a variety of purposes, including Frskolin skin rashes, asthma, bronchitis, insomnia, epilepsy, and Natural skin rejuvenation methods. Forskolin and blood pressure modern interest is based almost entirely on the work of a drug company, Hoechst Pharmaceuticals. Like other drug manufacturers, Hoechst regularly screens medicinal plants in hopes of discovering new medications. Inwork performed in collaboration with the Indian Central Drug Research Institute found that the rootstock of Coleus forskohlii could lower blood pressure and decrease muscle spasms. Intensive study identified a substance named forskolin that appeared to be responsible for much of this effect. Like certain drugs used for asthma, forskolin increases the levels of a fundamental natural compound known as cyclic AMP.
