Polygala Tenuifolia: An overview
Polygala tenuifolia, also known as Chinese Senega or Yuan Zhi, is a plant species that is native to China and is used in traditional Chinese medicine. It is a protected species due to its medicinal importance. It has a variety of pharmacological activities that contribute to its therapeutic effects.
The plant is cultivated in various regions, and studies have shown that the wild population of Polygala tenuifolia exhibits a higher genetic diversity level than the cultivated population [1].
Moreover, analysing the inorganic elemental fingerprint of the cultivated Polygala tenuifolia can help us pinpoint its geographic origin [2].
Benefits of Polygala tenuifolia
Improves cognitive functioning: Polygala tenuifolia is used to treat many medical conditions. One of the critical benefits of Polygala tenuifolia is its potential to improve cognitive function. Due to this property, it is a potential treatment for Alzheimer's disease. Studies have also been conducted to show that it enhances learning and memory. [3].
Calming effect on the Mind: Polygala tenuifolia also has a soothing effect on the mind. This is beneficial for treating those suffering from Depression, Anxiety and insomnia [4, 5]. It has been used traditionally to treat these conditions, and modern research supports its effectiveness.
Anti-inflammatory properties: In addition to its cognitive and calming benefits, Polygala tenuifolia has been found to have anti-inflammatory properties. It can inhibit the production of pro-inflammatory cytokines, proteins that promote inflammation [6]. This makes it valuable for the treatment of inflammatory diseases.
Neuronal damage resistance: Polygala tenuifolia has been shown to have neuroprotective effects. It can prevent neuronal damage, which is yet another reason it is beneficial in treating Alzheimer's disease [3].
Enhances immunity: Polygala tenuifolia contains an essential polysaccharide, which has been found to have immune activity, promoting cell proliferation and activating effectors to release cytokines, which activate macrophages for immune activity [7].
Side effects of Polygala tenuifolia
Gastrointestinal irritation: One of the potential side effects of Polygala tenuifolia is gastrointestinal irritation. This is mainly observed with the consumption of raw Polygala Radix, which can irritate the throat and cause discomfort in the gastrointestinal tract after long-term use or excessive doses. The main toxic components causing this irritation are saponins [4].
Interacts with other medications: Polygala tenuifolia contains specific compounds that inhibit chlorzoxazone 6-hydroxylation catalysed by CYP2E1, a crucial enzyme in drug metabolism. This suggests that Polygala tenuifolia could interact with other medications and affect their metabolism [4].
Dosage and toxicity: Studies have shown that Polygala tenuifolia is safe in proper dosage. However, it does have potential Risks at high doses.[8, 9]. This is why it's essential to use a dosage your physician prescribes.
Advise Precaution
It's crucial to acknowledge that although Polygala tenuifolia has been used in traditional medicine for centuries, we still need to understand its effects and interactions with other substances fully. Therefore, more research must be done on the subject. It's always best to consult a healthcare provider before starting any new treatment regimen to prevent potential side effects.
