Gou Teng extract 4% | Uncaria rhynchophylla

Properties: Gou Teng is not so common in Europe yet, but quite famous in China and Japan, where it has been used in traditional medicine for millennia. Ancient herbalists have used it in the therapy of such serious diseases as e.g. epilepsy. This alone shows how potent is its impact on the central nervous system. Let’s take a look at how Uncaria rhynchophylla actually works and what are its main effects on the organism. Generally speaking, Gou Teng helps the brain to reach and maintain an optimal level of activity.

On one hand, it stimulates the neuronal metabolism, which speeds up information processing. The active compounds found in U.rhynchophylla dilate the blood vessels of the brain, thereby providing its cells with more nutrients. What is more, they improve the activity of their energy centers – mitochondria – thus allowing efficient exploitation of the additional resources. Noteworthy, they also upregulate the secretion of acetylcholine – a key excitatory neurotransmitter involved in the process of information acquisition and processing. All these effects combined ensure that the supplementation of Gou Teng’s extract brings about a noticeable improvement of cognitive abilities. In sum, it helps us to learn new pieces of knowledge faster and remember them longer.  

On the other hand, the extract of U.rhynchophylla protects the brain from overexcitability, while simultaneously ensuring that its hard work is properly rewarded. Clinical trials and other experiments have shown that its administration results in enhanced activity of dopaminergic and serotoninergic receptors. These two neurotransmitters are intrinsically connected to the feeling of satisfaction, inner balance, and stress resilience. This double effect of Gou Teng is noticeable even after a single dose – participants have observed a clear improvement of both psychological well-being and intellectual performance. This supplement goes very well with a morning cup of coffee – not only improves its taste, but also its properties.

Occurrence: The species Uncaria rhynchophylla, of the genus Uncaria, is a flowering climber from the Rubiaceae family. This plant is native to China and Japan. Typical for this plant is the presence of small hooks on the stem, which allow it to climb over the trunks and branches of other plants. These thorny shoots, devoid of leaves, are the raw herbal material. The inflorescences are spherical and consist of small flowers with yellow petals and red stamens.

In traditional Chinese medicine (TCM) and Japanese medical system (Kampo) the shoots of Uncaria rhynchophylla have been applied as a remedy to headaches, dizziness, epilepsy, insomnia, and hypertension. The plant is also appreciated for its toning properties – for example its extract can soothe sudden attacks of excitation or aggression that sometimes accompany dementia.

Biochemistry: The substances to which Uncaria rhynchophylla owes its properties include: hirusteine, corinoxin, rhynchophylline. Apart from them, the plant also contains: organic acids, rutin, alkaloid glycosides, catechins, triterpenes, alkaloids.

Fun fact: Uncaria rhynchophylla is commonly known as Gou Teng. This Chinese name literally means “fishing hook” and is a reference to distinctive hooks that grow all over the shoots of this plant. This is also reflected in its latin name. The first part – Uncaria – comes from the word uncus, which means “hook”. The second part – rhynchophylla – literally means “horn-shaped leaves”.

How does Gou Teng extract 4% | Uncaria rhynchophylla work?

Soothes stress symptoms: Serotonin is not only responsible for mood regulation. Its optimal activity helps us to deal with adversarial circumstances efficiently. The results of scientific studies have proven that Uncaria rhynchophylla relieves stress symptoms such as anxiety or fear. Clinical trials demonstrated that already a single dose of Gou Teng extract was sufficient to improve stress resilience. After just a week of supplementation, the results were comparable to effects of a prescription drug used as a reference.

Supports the nervous system: Multiple research studies show that Gou Teng positively influences the central nervous system. Bioactive compounds found in this plant support the functioning of mitochondria, which are the powerhouse of the cells. This improves the efficiency of neuronal signal transmission, even when the availability of oxygen and nutrients is scarce. Moreover, Uncaria rhynchophylla helps to control the immune response of glial cells, which prevent damage of the central nervous system. Lastly, it upregulates the activity of acetylcholine – a neurotransmitter crucial for optimal cognitive performance, especially in terms of learning and memory.

Improves the mood: Serotonin and dopamine are major neurotransmitters that have an important role in regards to mental well-being. The first one is commonly known as the “happiness hormone” because its balanced activity is crucial for emotional stability and comfort. The second one is related to the reward system in the brain. Dopamine release induces feelings of motivation, satisfaction and pleasure. Research confirms that active compounds of Gou Teng stimulate serotonergic receptors 5-HT1A. It has also been proven that geissoschizine contained in this herb has a high affinity to D2 dopaminergic receptors. Thanks to those mechanisms, extract from Uncaria rhynchophylla upregulates the activity of serotonin and dopamine, which may improve general mood.

Benefits general health condition: Uncaria rhynchophylla has beneficial effects not just on the brain, but on the entire organism – especially the cardiovascular system. It is proven  that active compounds found in this plant help to control the blood pressure. They increase the production of nitric oxide, which dilates the blood vessels. Therefore, the blood can flow easily and can reach all the tissues, delivering oxygen and nutrients crucial for their optimal functioning. Gou Teng is also an immunomodulator. This means that it regulates the operations of the immune system. It is especially beneficial when the Th1 lymphocytes become overactive, which often happens during allergic reactions or the development of the symptoms of atopic dermatitis.
