He Shou Wu Stem (Ye Jiao Teng) Function and Efficacy Recorded in TCM
Yejiaoteng is a commonly used calming medicine in traditional Chinese medicine, which also has the function of promoting blood circulation and dispelling wind. It is actually the vine stem of Polygonum multiflorum, hence it is also known as’ Shouwu vine ‘. Its medicinal properties are mild, with a sweet and slightly bitter taste, and it belongs to the heart and liver meridians.

The following are the detailed roles and applications of night wisteria in traditional Chinese medicine theory:
1. Nourish the heart and calm the mind
This is the most important and core function of Night Vine.

Mechanism of action: Its medicinal properties are peaceful, its taste is sweet and can nourish, it mainly enters the heart and liver meridians, can nourish yin blood, nourish the heart and calm the mind.

Main applications:
Insomnia caused by Yin deficiency and lack of blood: This is the area where Yejiaoteng excels the most. Especially suitable for insomnia caused by insufficient liver and liver yin blood, leading to disturbance of yang and restlessness. This type of insomnia often manifests as:f

Difficulty falling asleep, or easily waking up and having multiple dreams after sleeping.

Accompanied by symptoms such as palpitations, forgetfulness, dizziness, tinnitus, and pale complexion.

Often combined with Acacia bark: Yejiaoteng is often paired with Acacia bark to form a medicinal pair, known as “Yejiaoteng Acacia bark”. Both have the effect of calming the mind and relieving depression, but the night vine tends to nourish the heart and calm the mind, while the acacia bark tends to relieve depression and calm the mind. They are mutually beneficial and have a better effect on those who are restless, depressed, and irritable.

2. Eliminate wind and unblock meridians
Yejiaoteng also has good joint promoting and rheumatism dispelling effects.

Mechanism of action: Most rattan medicinal herbs have the property of promoting blood circulation, known as “using rattan to promote blood circulation”. Yejiaoteng can nourish blood and promote blood circulation, relax tendons and activate collaterals, and eliminate the evil of rheumatism in the meridians.

Main applications:
Blood deficiency and body pain: suitable for limb soreness, numbness, and poor joint flexion and extension caused by insufficient Yin blood, loss of muscle and pulse nourishment, and rheumatism.

Rheumatoid arthritis: It can be used to treat various types of rheumatoid arthritis, especially suitable for patients with a long course of disease and accompanied by symptoms of blood deficiency.

3. Nourish blood, dispel wind and relieve itching
This is a rather special but very practical effect.

Mechanism of action: Traditional Chinese Medicine believes that “blood deficiency generates wind”, which means that deficiency of yin and blood can cause the skin to lose nourishment, resulting in internal movement of deficiency wind, manifested as itching. Yejiaoteng nourishes the skin by nourishing blood and can dispel wind, thus achieving the effect of relieving itching.

Main applications:
Skin itching: It has a good effect on elderly skin dryness and itching, winter skin itching, and other conditions that belong to blood deficiency and wind dryness. Take it orally regularly, or wash it outside with a large amount of Night Vine Decoction.

Modern Pharmacological Effects of He Shou Wu Stem (Ye Jiao Teng)
The modern pharmacological research on Yejiaoteng has been quite in-depth, and these studies have scientifically confirmed the rationality of its traditional Chinese medicine efficacy, especially in sedation, hypnosis, and treatment of skin diseases.

The following are the main modern pharmacological effects of Yejiaoteng:
1. Sedative and hypnotic effects

This is the most prominent and extensively studied pharmacological effect of the night vine, directly confirming its traditional efficacy of “nourishing the heart and calming the mind” in treating insomnia.

Mechanism of action:
The extract of Yejiaoteng (especially anthraquinone and glycoside components) can significantly inhibit the excitability of the central nervous system.

It can bind to benzodiazepine receptors in the brain, enhancing the function of gamma aminobutyric acid (GABA, a major inhibitory neurotransmitter), thereby producing sedative, anti anxiety, and hypnotic effects similar to modern sleeping pills.

Research has shown that it can prolong total sleep time, especially slow wave sleep (deep sleep), and shorten the time required to fall asleep.

Application: This provides a solid scientific basis for its use as a natural and mild sleep aid medication.

2. Anti inflammatory, antibacterial, and immunomodulatory effects
This part of the effect is closely related to its efficacy of “dispelling wind, unblocking collaterals, and relieving itching”.

Anti inflammatory: Flavonoids, polysaccharides, and other components in night wisteria can significantly inhibit the release of various inflammatory factors (such as tumor necrosis factor – α, interleukin, etc.), and have a clear anti-inflammatory effect on experimental inflammatory models (such as toe swelling and ear swelling).

Antibacterial: In vitro experiments have shown that the decoction of night wisteria has varying degrees of inhibitory effects on various pathogenic bacteria such as Staphylococcus aureus, Escherichia coli, and Shigella.

Immune regulation: Polysaccharides from Polygonatum sibiricum can enhance the phagocytic ability of macrophages, promote lymphocyte transformation, and thus regulate the immune function of the body.

Application: This explains why Yejiaoteng can be used to treat rheumatoid arthritis (anti-inflammatory) and skin infections, itching (antibacterial, anti-inflammatory).

3. Reducing blood fat and anti atherosclerosis
This is consistent with the source effect of Polygonum multiflorum in nourishing essence and blood.

Function: Yejiaoteng can reduce the levels of serum total cholesterol, triglycerides, and low-density lipoprotein (“bad” cholesterol) in experimental hyperlipidemic animals.

Mechanism: It may be achieved by promoting lipid metabolism and excretion, as well as protecting vascular endothelial cells.

Application: It suggests its potential value in preventing and treating cardiovascular and cerebrovascular diseases.

4. Effects on the cardiovascular system
Function: The extract of Polygonatum sibiricum has the effect of dilating coronary arteries and increasing coronary blood flow, and has a protective effect on myocardial ischemia. At the same time, it can also slightly lower blood pressure.

Application: This provides additional benefits for its use in treating patients with cardiovascular and cerebrovascular diseases accompanied by insomnia and anxiety.

5. Other functions
Antioxidant: The phenolic acids and flavonoids in night wisteria have good ability to scavenge free radicals, which helps to delay cell aging.

Antitumor: Some preliminary studies have shown that its extracts have inhibitory effects on certain cancer cell lines, but research in this area is still in its early stages.
