Nature of Polygala Tenuifolia
Polygala tenuifolia is a perennial plant in the Polygalaceae (Potato) family. It is native to East Asia, including China, Korea, and Japan, and has been used for almost 2,000 years in traditional Chinese medicine. The plant can reach a height of 50 cm and has lance-shaped leaves and little purple flowers. The most often used component of the plant is the root, which contains a number of bioactive chemicals, including saponins, flavonoids, and triterpenoids that contribute to its cognitive-enhancing qualities.
Health Benefits of Polygala Tenuifolia
Polygala tenuifolia has been well-researched for its ability to improve cognitive performance and treat various neurological illnesses. It has been shown to stimulate the synthesis of brain-derived neurotrophic factor (BDNF), a protein that promotes neuron growth and survival in the brain. BDNF is essential for learning and memory, and its lack has been related to a variety of neurological illnesses, such as Alzheimer’s disease, depression, and anxiety.
Animal studies have revealed that Polygala tenuifolia improves working memory, attention, and overall cognitive performance. Researchers discovered that Polygala tenuifolia extracts greatly enhanced spatial working memory in rats in a study published in the Journal of Ethnopharmacology and increased attention and working memory in rats in another study published in the Journal of Natural Medicines.
Polygala tenuifolia has also been investigated for its effects on mood regulation. Researchers discovered that Polygala tenuifolia extract showed antidepressant-like effects in mice in a study published in the Journal of Neuroscience Research and anxiolytic effects in mice in another study published in the Journal of Pharmacology and Experimental Therapeutics.
Polygala tenuifolia has traditionally been used to support respiratory health and alleviate cough, asthma, and bronchitis symptoms. Its compounds may help relax bronchial smooth muscles, reduce inflammation in the respiratory tract, and inhibit excessive mucus production, thereby improving breathing and lung function.
Chemistry of Polygala Tenuifolia
Polygala tenuifolia includes several bioactive chemicals that contribute to its nootropic properties. Saponins, flavonoids, triterpenoids, and xanthones are examples of these chemicals. Saponins comprise polygalasaponins and onjisaponins, the most thoroughly investigated chemicals. They are thought to be the principal active components of Polygala tenuifolia and have been proven to have a variety of pharmacological activities, such as anti-inflammatory, antioxidant, anti-cancer, and neuroprotective capabilities.
Physiological Mechanisms of Action
Polygala tenuifolia’s ability to stimulate the generation of brain-derived neurotrophic factors (BDNF) is principally responsible for its cognitive-enhancing properties. BDNF is a protein essential for neuron growth and survival in the brain. It is required for learning and memory, and its lack has been linked to various neurological diseases.
Polygala tenuifolia has also been proven to influence the action of neurotransmitters such as dopamine, serotonin, and glutamate. Dopamine is a neurotransmitter involved in reward and motivation, whereas serotonin regulates mood. Glutamate is the brain’s principal excitatory neurotransmitter and is required for learning and memory.
Polygala tenuifolia‘s effects on neurotransmitter activity are thought to be mediated through its ability to prevent neurotransmitter reuptake. By inhibiting reuptake, Polygala tenuifolia improves the availability of these neurotransmitters in the synaptic cleft, which can contribute to better cognitive performance.
Polygala tenuifolia contains antioxidant compounds that scavenge free radicals and reduce oxidative stress in cells and tissues. By neutralizing reactive oxygen species (ROS) and inhibiting lipid peroxidation, Polygala tenuifolia helps protect against oxidative damage to biomolecules such as proteins, lipids, and DNA. The antioxidant activity of Polygala tenuifolia may contribute to its neuroprotective, cardioprotective, and anti-aging effects.
Optimal Dosage of Polygala Tenuifolia
The dose of Polygala tenuifolia varies depending on the individual and the intended benefits. However, most studies have employed daily doses ranging from 50 to 500 mg. To reduce the danger of adverse effects, it is best to begin with a low dose and gradually increase it to the desired level.
Side Effects of Polygala Tenuifolia
When consumed at the recommended amounts, Polygala tenuifolia is usually regarded as safe. However, some people may encounter minor side effects such as nausea, dizziness, and headache. These adverse effects are generally transient and disappear with continuing use.
