Found growing wild in gardens, rice fields, and roadside patches across Vietnam, gotu kola is one of the country’s most popular herbal drinks. Long valued in traditional medicine, the humble leaf is now attracting scientific interest for its potential benefits for skin health, sleep quality, and inflammation.
On a hot afternoon in Vietnam, there’s a good chance you’ll spot someone sipping a glass of rau má, or gotu kola juice.
The bright green drink is a summer staple, prized for its cooling taste and reputation as a natural remedy for everything from heat exhaustion to skin problems. While many Vietnamese grow the plant at home or gather it from gardens and fields, interest in gotu kola has expanded far beyond Southeast Asia in recent years as researchers continue to study its bioactive compounds.
Can Gotu Kola Really Protect Your Skin?
One reason gotu kola has become a popular ingredient in skincare products is its rich concentration of compounds known as triterpenoids, including asiaticoside and madecassoside.
Research suggests these compounds may help support collagen production and assist the skin’s natural repair processes. The plant also contains antioxidants that can help reduce oxidative stress, one of the factors associated with skin aging.
Some studies have found that these antioxidants may help reduce cellular damage caused by UV exposure. However, experts stress that drinking gotu kola juice is not a substitute for sunscreen. At best, it may offer supportive benefits as part of a broader skincare routine.
A Traditional Remedy for Stress and Sleep
Beyond skincare, gotu kola has long been used in traditional Asian medicine as a calming herb.
Some evidence suggests that compounds in the plant may help support relaxation and reduce feelings of stress and anxiety. In Vietnam, it is often consumed in the afternoon or evening by people looking for a natural way to unwind after a long day.
While researchers are still studying its effects, gotu kola’s reputation as a gentle, calming herbal remedy remains one of the reasons for its enduring popularity.
Potential Benefits for Joints and Recovery
Gotu kola also contains minerals such as calcium and magnesium, along with naturally occurring anti inflammatory compounds.
These properties have led researchers to investigate its role in supporting connective tissue health and recovery. Although it should not be viewed as a treatment for joint conditions, some studies suggest it may help support overall musculoskeletal health when combined with a balanced diet and healthy lifestyle.
More Than Just a Summer Drink
For many Vietnamese, the appeal of gotu kola extends beyond any single health claim.
The herb has traditionally been associated with cooling the body during hot weather, supporting circulation, and helping the skin recover from minor irritation. Modern research is still catching up with many of these traditional uses, but its popularity has remained remarkably consistent.
Don’t Overdo It
Like many herbal products, more is not always better.
Health experts generally recommend consuming gotu kola in moderation. Excessive intake may cause digestive discomfort in some people, while individuals with certain medical conditions, including liver disease, or those taking medication should consult a healthcare professional before using it regularly. Pregnant women should also seek medical advice before adding it to their routine.
In a country filled with trendy wellness products and imported superfoods, gotu kola remains refreshingly simple. It is inexpensive, widely available, and deeply rooted in everyday Vietnamese life. Whether enjoyed for its potential health benefits or simply as a refreshing drink on a humid afternoon, it continues to hold a special place in Vietnam’s food culture.
