Jiaogulan tea has become increasingly popular for its numerous health benefits and calming effects, making it a sought-after herbal remedy. Among the questions surrounding this tea, one inquiry stands out: does jiaogulan tea contain caffeine? Understanding the caffeine content of jiaogulan tea is crucial for those seeking a caffeine-free alternative to traditional teas or exploring its health benefits. In this comprehensive article, we will explore the caffeine levels in jiaogulan tea and its potential health benefits. 

What is jiaogulan tea?

Jiaogulan tea, also referred to as Southern Ginseng or the Immortality Herb, is a type of herbal tea made from the leaves of the Gynostemma pentaphyllum plant. This plant is a climbing vine that is native to China and other parts of Asia. For thousands of years, Jiaogulan has been an integral component of traditional Chinese medicine, renowned for its remarkable ability to alleviate a multitude of conditions such as inflammation, cardiovascular disorders, and diabetes.

In terms of taste, jiaogulan tea is often described as having a slightly sweet and earthy flavor. When compared to the taste of green tea, it is generally milder and less astringent. Jiaogulan tea is often brewed like traditional tea leaves, either loose or in tea bags. Some people describe it as having a refreshing and clean taste, making it enjoyable to drink either hot or cold.

Due to its high bioactive compounds (saponin, flavonoid, polysaccharide) and anti-aging and health-promoting properties, jiaogulan tea has become a popular herbal tea all over the world. It has gained popularity around the world due to its unique flavor as well as its perceived medicinal value derived from traditional Chinese medicine practices over centuries. Overall, it’s a popular choice for those looking to incorporate herbal remedies into their wellness routine.

Does jiaogulan tea have caffeine?

Jiaogulan tea is known for its naturally low caffeine content, similar to other herbal teas. However, when compared to popular traditional teas such as green tea or black tea, which typically have higher caffeine levels, jiaogulan tea is often regarded as either caffeine-free or extremely low in caffeine content. Nevertheless, the scientific community has conflicting views regarding the exact caffeine content in this tea. So, does jiaogulan tea have caffeine? 

Several studies have found no detectable levels of caffeine in jiaogulan tea. A notable example is a meticulously conducted 2014 study featured in the prestigious Journal of Chromatographic Science, which meticulously examined the chemical composition of jiaogulan and unequivocally failed to detect any content of caffeine. This shows that jiaogulan tea is a naturally caffeine-free beverage.

However, there are also reports suggesting that jiaogulan tea might possess minimal levels of caffeine, although it is much less than what is found in typical caffeinated drinks such as coffee or black tea. In 2005, a study published in the Journal of Agricultural and Food Chemistry discovered trace amounts of caffeine in jiaogulan samples, with quantities varying between 0.05 and 0.15 milligrams per gram of dried leaves.

Even if jiaogulan tea does contain a small amount of caffeine, it is not enough to have a significant stimulant effect. Caffeine is known for increasing alertness and energy levels, but this typically requires higher doses. However, individuals may react differently to caffeine, and even small amounts can cause negative side effects in some people. Therefore, those who are sensitive to caffeine or have certain health conditions should be cautious when consuming jiaogulan tea.

How can jiaogulan tea support human health?

Jiaogulan tea is highly valued for its extensive range of alleged health advantages, which arise from its abundant assortment of bioactive compounds. The presence of saponins, flavonoids, and polysaccharides in jiaogulan is thought to offer antioxidant, anti-inflammatory, and immunomodulatory properties that have the potential to combat various diseases.

Support cardiovascular health

It is believed that jiaogulan can positively impact cardiovascular health by reducing inflammation and preventing the harmful effects of stress on the body, including fluctuations in blood pressure. It may also improve circulation and support healthy cholesterol levels due to the presence of saponins, which have the ability to bind to and reduce cholesterol. Research suggests that incorporating jiaogulan into your routine may lower overall cholesterol levels and raise levels of beneficial HDL cholesterol.

Adaptogenic effects

Jiaogulan is frequently categorized as an adaptogen, which has the potential to adjust to various stressors and foster a state of balance and resilience. By doing so, it can enhance both mental and physical well-being, particularly during periods of stress. The mechanism behind the adaptogenic properties of Jiaogulan involves its role in regulating the levels of stress hormones, such as cortisol, within the body. When these hormones are present in excessive quantities, they can lead to some symptoms, including disruptions in sleep patterns, digestive issues, and compromised metabolic health.

Anticancer properties

Jiaogulan tea has a high concentration of antioxidants, specifically flavonoids and saponins. These antioxidants can help fight against oxidative stress and lower the likelihood of chronic diseases. Some research suggests that the antioxidants found in gynostemma, a component of Jiaogulan tea, may be able to inhibit the spread of cancer cells. Additionally, studies have shown that gynostemma has antioxidant and anti-inflammatory properties that can promote apoptosis and repair damaged DNA, protecting against some types of cancer, such as colon cancer.
