What can gotu kola do for me?
Boost microcirculation, collagen and skin repair with centella
The Ayurvedic South Asian herb gotu kola / centella asiatica (also known as hydrocotyle, asiatic pennywort, Indian pennywort and tiger grass) is traditionally used in herbal teas and salads in several Asian countries and in Madagascar. Gotu kola has been used for millennia as a traditional skin medication - and for good reason. Research has shown that centella asiatica / gotu kola is one of the most important anti-ageing, skin repairing, skin firming and anti-cellulite actives known today.
Recently centella has become the new fashionable anti-ageing active in cosmetics and food supplements, used by more and more large skincare and nutrition brands. We, at LipoTherapeia, have been using gotu kola in our skincare products, our cellulite treatments and our anti-aging treatments for fifteen years and are happy to share our knowledge of this impressive plant with you, summarising the most important research on the skin benefits of centella asiatica, below.
Although it is unlikely to become as popular as turmeric or green tea any time soon, centella is still gaining recognition and is becoming more and more common in skincare and clinical nutrition, due to its multiple medicinal properties.
Asiatic acid, madecassic acid, madecassoside & asiaticoside
The skin and health benefits of centella asiatica are the sum of its four main active ingredients: asiatic acid, madecassic acid, madecassoside and asiaticoside. This page is all about exploring the therapeutic benefits of centella asiatica / gotu kola on the skin and overall health and wellbeing.
25 amazing skin benefits of gotu kola / centella asiatica

Centella asiatica and cellulite
As you can see from the list above, centella works on all seven aspects of cellulite (bold type on the list above), and that makes her one of the most important anti-cellulite ingredients, hence its use in anti-cellulite products for decades now.
The only thing that was missing from those creams up to now was concentration. For cost/profitability reasons, most such creams contain very little in the way of active ingredients, centella or others (see below).
Boost your whole body health with gotu kola
Although we specialise in skin care it would not be an omission if we neglected to mention to overall health benefits of centella asiatica.
According to a pharmacological review in 2010, centella asiatica may help with mental focus/cognition; relax an overactive mind and reduce anxiety and depression (sedative, anxiolytic and antidepressant properties); it has also been investigated for its action against Alzheimer's, epilepsy, gastric ulcers, viral infections and pain/inflammatory conditions.
(Source: Pharmacological Review on Centella asiatica: A Potential Herbal Cure-all)
Since then many more studies have been conducted on centella's health properties - a total of 650 studies by the end of 2017.
Centella asiatica cream for skincare/cellulite
For all the reasons described above, concentrated extracts of centella asiatica / gotu kola, rich in the four triterpenes mentioned above, are of great importance as active ingredients in anti-cellulite, anti-ageing, leg wellness, skin brightening, skin firming, stretch mark and under-eye creams.
Although centella has been used by European doctors for vein conditions, wound healing and anti-aging for more than fifty years, it is much less known in the United States or Britain. Nevertheless, more and more people are now becoming aware of centella food supplements, herbal teas, cellulite creams, anti-aging creams, facials and cellulite treatments.
Pure asiatic acid, madecassic acid, asiaticoside and madecassoside (creams & treatments)
Our Celluence® creams are the only cellulite creams in the world with high concentrations of 95%+ pure TTFA (total triterpenic fraction of centella asiatica), i.e. ALL FOUR centella asiatica actives! And they also contain 39x other natural anti-cellulite actives.
Our Meso-CRF® Facial | Centella and Meso-CRF® Body | Centella are the first and only anti-ageing facial treatment and anti-cellulite treatment in the world, respectively, to utilise Deep Tissue Radiofrequency™ and 100% purified centella asiatica extract - pure asiatic acid, madecassic acid, asiaticoside and madecassoside.
More about the centella asiatica plant
What's in centella asiatica?
What is the percentage of actives in a typical cup of gotu kola tea or in the leaves of the plant?
Dried gotu kola leaves contain about 0.8% of the total of asiatic acid, asiaticoside and madecassoside, according to a study published in 2014. Although madecassic acid was not measured, it would probably follow the pattern of the other three actives, for a total of about 1% of actives in dried gotu kola leaves.
This means that a double strength 2g centella tea portion contains about 20mg of the four actives. Most studies on centella used 100mg of actives a day, i.e. five double strength cups of gotu kola tea are required to reach that therapeutic level.
[Source: Quantitative Estimation of Asiatic acid, Asiaticoside & Madecassoside in two accessions of Centella asiatica (L) Urban for Morpho-chemotypic variation]
What is the relative percentage of the four actives in centella asiatica leaves?
According to this study, methanolic extraction of the four triterpenes in the gotu kola plant yielded 6% asiatic acid, 28% madecassic acid, 13% asiaticoside and 53% madecassoside. This shows that the actual plant contains more madecassic acid and is geared more towards skin healing than skin tightening, as opposed to TECA and TTFCA extracts, which are more tuned towards skin tightening.

Some pictures of one of our own gotu kola plants :)
Gotu kola plants need constant watering (every second day), sunshine and warmth, but if you provide them with those elements they grow quickly. This is one of our centella plants. From time to time we nib a leave to eat raw or a few leaves to make a home made gotu kola tea. You need to have a small plantation to get a constant supply of centella for the five double strength teacups per day recommended by research, but even the occasional tea is an interesting treat, especially for us that we are so passionate about centella extracts.

...suppleness, firmness, roughness and skin hydration and skin elasticity, repairing the elastic fibre network in the papillary dermis, after six months of treatment. The study authors state that their "results revealed a functional and structural remodelling of chronically sun-damaged skin". Given the extremely low amount of madecassoside acid in the cream (for reasons of cost-cutting, as madecassoside is 10x more expensive then vitamin C), even more impressive results should be expected with a more significant 1% madecassoside concentration.

61/ Asiaticoside reduces crow's feet (periorbital wrinkles) in double blind, placebo controlled study
Application of an asiaticoside cream twice a day for 12 weeks improved periorbital wrinkles on 65% of volunteers, with 12% experiencing complete wrinkle elimination and 23% not having a significant improvement. With the addition of the other three triterpenes and an increase in concentration, even more impressive results should be expected. (Source: Evaluation of the effects of a preparation containing asiaticoside on periocular wrinkles of human volunteers)
60/ Centella overcomes cortisone's wound-healing suppression...
...and significantly promotes wound healing. Extract-treated wounds were found to epithelise faster, the rate of wound contraction significantly increases and wet and dry granulation tissue weights, granulation tissue breaking strength, and hydroxyproline content in a dead space wound model also increase. In summary, the extract of the centella asiatica leaf extract has the effect of attenuating the known effects of dexamethasone healing in all wound models. (Source: Effect of Centella asiatica L (Umbelliferae) on normal and dexamethasone-suppressed wound healing in Wistar Albino rats)
59/ Centella asiatica accelerates wound healing and hyaluronic acid / collagen synthesis
Titrated extract of centella asiatica (TECA) increases dry weight, DNA, total protein, collagen, glycosaminoglycans and uronic acid in treated wounds, as well as levels of hydroxyproline, showing an increased remodeling of the collagen matrix in the wound. Asiatic acid and asiaticoside was found to be the most active of the 3 triterpenes, with asiaticoside exerting a preferential stimulation of collagen synthesis, at low doses only. (Source: Triterpenes from Centella asiatica stimulate extracellular matrix accumulation in rat experimental wounds)
58/ Centella asiatica acts on multiple phases of wound repair
Centella asiatica extract increases cellular proliferation and collagen synthesis at the wound site, as evidenced by increase in DNA, protein and collagen content of granulation tissues. Quicker and better maturation and crosslinking of collagen is observed in extract-treated skin, as indicated by the high stability of acid-soluble collagen and increase in aldehyde content and tensile strength. The extract treated wounds is found to epithelialise faster and the rate of wound contraction is higher, as compared to control wounds.

Centella asiatica is a medicinal plant that has been in use since prehistoric times and is used in folk medicine to treat a wide range of indications. However, in contrast to other medicinal plants, centella asiatica and its triterpenes have been subjected to quite extensive experimental and clinical investigations. Studies conducted in accordance to standardised scientific criteria have shown it to have a positive effect in the treatment of venous insufficiency and stretch marks (striae) and wound healing.

The studies showed that the higher dose of centella asiatica (120mg of TTFCA per day) offered the most impressive results. Higher doses producing better results, there were no side effects and the placebo group experienced no results at all. Furthermore, all the above changes were shown to protect diabetics from microangiopathy and progression to clinical stages.

In this study it was found that gotu kola extract stimulates collagen synthesis (better than vitamin C), lipolysis (better than that of caffeine), exhibits potent antioxidant / free radical scavenging activity (equal to that of grape seed extract and vitamin C) and exhibits similar UV protection effect to oligomeric cyanidins (Source: Triterpene Composition and Bioactivities of Centella asiatica)

5/ Centella and pine bark combination helps prevent atherosclerosis...
...by halting the accumulation of arterial plaques and their progression to clinical stages, mainly via reducing oxidative stress (Source 1: Pycnogenol® and Centella asiatica to prevent asymptomatic atherosclerosis progression in clinical events; Source 2: Pycnogenol® and Centella asiatica in the management of asymptomatic atherosclerosis progression)
4/ The combination of centella asiatica, esculoside caffeine and L-carnitine maximise lipolysis by inhibiting alpha-2 adrenoreceptors
In vitro tests demonstrated (a) a dramatic increase in the cyclic adenosine monophosphate (cAMP) content in human adipocytes, with a subsequent rise in the nonesterified fatty acids (NEFA) content of human adipocyte incubation medium, and (b) in vivo studies showed an actual potent slimming effect on human volunteers. Moreover, the combination antagonises the alpha(2)-adrenergic receptor that is known to reduce intracellular AMPc content and, subsequently, to down-regulate lipolysis.

3/ gotu kola/centella asiatica can improve chronic venous insufficiency, lymphoedema and circulation impairment
Impaired skin microcirculation is a major contributing factor towards inflammation in patients with chronic venous insufficiency (CVI). Increase of capillary filtration rate predisposes to the formation of edema. Local lymphedema is a complication of CVI, often underdiagnosed. This paper, a review of randomised prospective controlled trials, shows that horse chestnut extract, flavonoids, total triterpenic fraction of centella asiatica (TTFCA) and procyanidins reduce capillary filtration rate and improve levels of partial pressures of oxygen and carbon dioxide in skin. The study found that combining with compression therapy may have some additive effects.

2/ Phlebitis ulcers heal with the aid of herbal cream consisting of gotu kola and other botanicals
This herbal compound, in combination with compression garments, significantly improved inflammation, healing time and pain in phlebitis, in relation to compression garments alone. Ivy extract in the cream contributed to pain reduction; horse chestnut, butcher's broom and grape seed extract reduced inflammation; and allantoin, gotu kola and hyaluronic acid aided sore healing. In patients who applied both the cream and the compression garment pain stopped in 72 hours, inflammation disappeared in one week, tissue swelling stopped in one week and healing was complete in 4 weeks.

1/ Review paper suggests gotu kola for the treatment of varicose veins and hemorrhoids
The loss of vascular integrity is associated with the pathogenesis of varicose veins. Several botanical extracts (horse chestnut/aesculus, butcher's broom/ruscus, gotu kola, flavonoids and pine bark) have been shown to improve microcirculation, capillary flow and vascular tone, and to strengthen the connective tissue of the perivascular amorphous substrate. Oral supplementation may prevent time-consuming, painful, and expensive complications of varicose veins and hemorrhoids (Source: Hemorrhoids and varicose veins: a review of treatment options)
