Gotu Kola

Pegged as the “herb of longevity,” gotu kola is a staple in traditional Chinese, Indonesian, and Ayurvedic medicine. Practitioners claim the medicinal plant has the power to boost brainpower, heal skin issues, and promote liver and kidney health — and some studies seem to agree.

Keep reading to learn how gotu kola may help improve your overall health and well-being.

 

It May Help Boost Cognitive Function

A small 2016 study (1) compared the effects of gotu kola extract and folic acid in boosting cognitive function after a stroke. This small study assessed the impact on three groups of participants — one taking 1,000 milligrams (mg) of gotu kola per day, one taking 750 mg of gotu kola per day, and one taking 3 mg of folic acid per day.

Although gotu kola and folic acid were equally beneficial in improving overall cognition, gotu kola was more effective in improving memory domain.

A separate study (2) looked at the cognitive enhancing effects of gotu kola water extract on mice. Although both young and old mice showed improvements in learning and memory using the Morris Water Maze, the effect was higher in the older mice.

 

It May Help Treat Alzheimer’s Disease

Gotu kola has the ability to enhance memory and nerve function, which gives it potential in treating Alzheimer’s disease. In fact, one 2012 study on mice (3) found that gotu kola extract had a positive effect on behavioral abnormalities in mice with Alzheimer’s disease.

The extract was also shown, in lab and animal studies, to have a modest effect on protecting brain cells from toxicity. This could also protect the cells from forming the plaque associated with Alzheimer’s.

Still, further research is needed to determine exactly how gotu kola could be used to treat Alzheimer’s. If you’re interested in adding this to your treatment plan, talk to your doctor before use.

 

It May Help Reduce Anxiety And Stress

Researchers in an animal study from 2016 (4) found that gotu kola had an anti-anxiety effect on male mice that were sleep deprived for 72 hours. Sleep deprivation can cause anxiety, oxidative damage, and neuroinflammation.

Mice that were given gotu kola for five consecutive days before undergoing sleep deprivation experienced significantly less anxiety-like behavior. They also experienced improved locomotor activity and less oxidative damage.

A 2013 review (5) of anti-anxiety herbal medicines also concluded that gotu kola has an acute anti-anxiety effect. However, more research is needed to confirm these findings.

 

It May Act As An Antidepressant

Gotu kola’s positive effect on brain function may also make it an effective antidepressant.

A review from 2016 (6) supports these findings, in part due to a study on 33 people with generalized anxiety disorder. The participants were asked to take gotu kola in place of their antidepressant medication for 60 days. They self-reported decreased stress, anxiety, and depression.

Another study discussed in the review assessed the effect of gotu kola on rats induced with chronic depression. The herbal remedy had a positive effect on certain elements of behavioral depression, including body weight, body temperature, and heart rate.

 

It May Improve Circulation And Reduce Swelling

Research from 2001 (7) found that gotu kola can reduce problems with fluid retention, ankle swelling, and circulation tied to taking flights that last longer than three hours.

Participants who experienced mild-to-moderate superficial venous disease with varicose veins were asked to take gotu kola for two days before their flight, the day of their flight, and the day after their flight.

Researchers found that participants who took the supplement experienced significantly less fluid retention and ankle swelling than those who didn’t.

Older research (8) has also shown that gotu kola can be useful in treating varicose veins. This may be because gotu kola has a positive metabolic effect on the connective tissue of the vascular wall.

 

It May Help Ease Insomnia

Given its perceived ability to treat anxiety, stress, and depression, gotu kola may also be used to treat the insomnia that sometimes accompanies these conditions. Some consider this herbal remedy to be a safe alternative to prescription medications used to treat insomnia and other sleep disorders.

Although older research (9) does suggest that gotu kola can help treat sleep disorders, additional studies are needed to confirm these findings.

 

It May Help Reduce Appearance Of Stretch Marks

According to a 2013 review (10), gotu kola can reduce the appearance of stretch marks. It’s thought that the terpenoids found in gotu kola increase collagen production in the body. This may help prevent new stretch marks from forming, as well as help heal any existing marks.

 

It May Promote Wound Healing And Minimize Scarring

Researchers in a 2015 study on rats (11) found that wound dressing containing gotu kola had healing effects on multiple types of wounds. This includes clean cuts by sharp objects, irregular tears caused by blunt-force trauma, and infected tissue.

Although promising, further research is needed to confirm these findings.

 

It May Help Relieve Joint Pain

The anti-inflammatory properties of gotu kola may be useful in treating arthritis.

In fact, one 2014 study (12) on collagen-induced arthritis in rats found that oral administration of gotu kola reduced joint inflammation, cartilage erosion, and bone erosion. Its antioxidant effect also had a positive effect on the immune system.

 

It May Have A Detox Effect

Newer research is taking a look at gotu kola’s effect on liver and kidney toxicity.

According to one 2017 animal study (13), gotu kola can be used to suppress the toxic side effects of the antibiotic isoniazid. Isoniazid is used to treat and prevent tuberculosis.

Rats were given 100 mg of gotu kola for 30 days before they were given the antibiotic. These rats experienced less toxicity overall. Rats that did experience toxicity in the liver and kidneys resumed to near-normal levels after being given gotu kola.
