Overview of Gotu Kola (Centella asiatica)

Gotu kola, scientifically known as Centella asiatica, is a perennial plant with a significant place in traditional medicine systems like Ayurveda and traditional Chinese medicine (TCM). Native to the wetlands of Asia, particularly in India, Sri Lanka, China, and Indonesia, this plant is characterized by its kidney-shaped leaves and small, pinkish-red flowers. Gotu kola belongs to the Apiaceae family and is renowned for its medicinal properties. (9) 

In traditional medicine, gotu kola has been cherished for centuries. In Ayurvedic medicine and TCM, gotu kola is considered a rejuvenating herb, known for enhancing mental clarity and promoting longevity. It has even been called one of the "miracle elixirs of life." It is valued for improving circulation, reducing inflammation, healing wounds, strengthening the connective tissues in the body, and relieving stress. The historical significance of gotu kola in traditional medicine underscores its importance as a natural remedy for various ailments, offering a holistic approach to health and wellness. (9) 

Phytochemical Components of Gotu Kola

The active compounds in gotu kola are responsible for its many pharmacological effects. Triterpenoid saponins, including asiatic acid, madecassic acid, and madecassoside, are believed to be the primary bioactive constituents responsible for many of gotu kola's medicinal properties. These compounds possess potent antioxidant, anti-inflammatory, antimicrobial, antitumor, and cardiovascular-protective properties. (9, 25) 

Gotu kola also contains essential oils, flavonoids, and tannins. Gotu kola leaves are also very nutritious, containing a variety of amino acids, fatty acids, vitamins, and minerals. (2, 9)

6 Therapeutic Uses of Gotu Kola

Based on scientific evidence, oral and topical administration of gotu kola may be recommended for patients hoping to optimize cognitive function, heal wounds, manage stress, promote healthy circulation, prevent aging, and treat musculoskeletal pain. 

1. Improving Memory and Cognitive Function 

Gotu kola's neuroprotective effects have primarily been explored in animal and in vitro studies, where the herb has shown promising results. In these studies, the active compounds in gotu kola, particularly triterpenoids, have demonstrated antioxidant properties, which help combat oxidative stress in the brain. Oxidative stress is a significant factor in the development and progression of neurodegenerative diseases. Additionally, research shows that gotu kola extract can protect the brain from glutamate-induced excitotoxicity and enhance neural connectivity. These effects suggest the herb's potential in promoting brain health and mitigating cognitive decline. (18) 

Clinical human studies have further validated these findings. Researchers have conducted trials to investigate gotu kola's impact on memory, cognitive function, and neurodegenerative diseases such as Alzheimer's. These studies have shown that gotu kola supplementation can improve memory and cognitive performance in human subjects (7, 24). The herb's neuroprotective properties are thought to contribute to these positive outcomes. As research continues, gotu kola's potential as a natural supplement for cognitive function and treating neurodegenerative diseases becomes increasingly promising. 

2. Wound Healing and Skin Repair 

Gotu kola's benefits for skin healing can be attributed to its rich content of triterpenoids, particularly asiaticoside and asiatic acid. When the skin is injured or wounded, inflammation and oxidative stress are common challenges the body faces. Triterpenoids in gotu kola act as powerful antioxidants, combating the harmful effects of oxidative stress and reducing inflammation. By doing so, they create an optimal environment for the skin's natural healing mechanisms to operate efficiently.

Moreover, triterpenoids in gotu kola stimulate type I collagen production. Collagen, a structural protein abundant in the skin, is essential for its strength, elasticity, and overall health. As triterpenoids boost collagen synthesis, they aid in forming new skin tissue, promoting faster wound healing and minimizing the appearance of scars. 

Clinical research shows that applying a 3% gotu kola cream to second-degree burns once daily increases the rate of complete healing by about one week, in addition to reducing dryness, itching, irritation, and scar severity, compared to silver sulfadiazine 1% cream.

3. Managing Stress and Anxiety 

Some studies suggest that gotu kola exhibits anxiolytic effects by enhancing GABA synthesis. GABA is an inhibitory neurotransmitter associated with having calming effects on the nervous system. Many pharmaceutical drugs for anxiety, stress, and insomnia work by increasing the effects of GABA in the brain. One study, including 40 participants, found that high doses of gotu kola helped improve the startle response, which is associated with stress and anxiety. 

4. Enhancing Circulation and Reducing Swelling 

Research has shown that gotu kola's triterpenoids strengthen blood vessel walls and reduce capillary permeability (9). These actions contribute to improved venous tone and reduced leakage of blood and fluid into surrounding tissues, addressing key issues in venous insufficiency and poor circulation. Clinical trials have demonstrated that using gotu kola for venous insufficiency in doses of 60-120 mg daily for 4-8 weeks results in improved microcirculatory parameters and rate of ankle swelling.

5. Anti-Aging Benefits of Gotu Kola

Chronic inflammation and oxidative stress are two causes of unhealthy and premature aging. As a potent antioxidant and anti-inflammatory agent, gotu kola can neutralize harmful free radicals responsible for cellular damage and acceleration of the aging process. By reducing oxidative stress and inflammation in the skin, gotu kola can help protect the skin from fine lines, wrinkles, age spots, irritation, and redness.

Gotu kola's roles in promoting collagen synthesis and microcirculation also offer powerful defenses against aging. Healthy collagen and blood flow maintain the skin's firmness and elasticity, ensure skin cells receive an adequate supply of oxygen and nutrients, and prevent puffiness.

6. Joint and Muscle Pain Relief 

The anti-inflammatory properties of gotu kola may help treat pain and arthritis. Experimental animal models have demonstrated the herb's ability to inhibit pro-inflammatory cytokines and pain pathways. These findings support the notion of using gotu kola effectively in treating conditions related to pain and rheumatism (arthritis). (15, 16) 

While more research, especially clinical trials, is needed to confirm the therapeutic value of using gotu kola for treating joint and muscle pain, a small study found that gotu kola decreased joint pain and improved finger movement in women with scleroderma.

Safety and Precautions

Gotu kola has been safely used in doses of up to 180 mg daily for up to one year or 1,000 mg daily for 60 days. Gotu kola is generally well-tolerated but may cause gastrointestinal upset (oral administration) or dermatological irritation (topical use) in some cases (11). 

Although rare, there are at least four case reports of hepatotoxicity associated with gotu kola use. The doses of gotu kola used in these cases were not reported, and hepatotoxic contaminants could not be ruled out. Still, patients with preexisting liver disease should use caution with oral herbal administration.

Gotu kola may also interact with the following medications (11):

• Hepatotoxic medications
• Cholesterol-lowering drugs
• Diabetes medications
• Diuretics
• Sedatives

It is always advised to consult a healthcare professional, especially if you have underlying health conditions or are taking medications, if you are considering gotu kola supplementation. This will help ensure the herb is safe and appropriate for your health needs, minimizing the risk of adverse effects or interactions.

How to Use Gotu Kola for Health

Gotu kola is available in tea, dried herb, tincture, capsule, tablet, and topical forms. Adults most commonly use herbal extracts in doses of 60-450 mg daily for 4-12 months. (11, 12)

Summary

Attributed mainly to its concentration of triterpenoids, gotu kola (Centella asiatica) is a potent herbal remedy used in traditional medicine for centuries. Its antioxidant and anti-inflammatory properties can be applied to treating various health concerns, including those pertaining to the neurological, integumentary, cardiovascular, and musculoskeletal systems. Future research efforts will continue to refine our understanding of this herb's diverse applications and therapeutic potential.
