Astragalus for Kidneys

Chronic kidney disease (CKD) is a widespread health condition affecting a substantial portion of the global population. There has been a growing recognition of the significance of alternative treatments and herbal remedies. Among these, Astragalus, a herb with a long-standing history in traditional Chinese medicine, emerges as noteworthy. Through its unique properties, Astragalus presents a compelling option for those seeking holistic approaches to address kidney disease.

Understanding Kidney Disease

Kidney disease encompasses a spectrum of types and stages, ranging from acute kidney injury (AKI) to chronic kidney disease (CKD). AKI typically arises suddenly due to factors like severe infections or insufficient blood supply, while CKD is a progressive condition that develops over time, often as a result of underlying health issues like hypertension or diabetes. These conditions are further stratified into stages, each indicating the severity of kidney impairment.

Common causes of kidney disease include uncontrolled high blood pressure, diabetes, kidney infections, and certain genetic predispositions. Additionally, lifestyle factors such as smoking and poor diet can exacerbate the risk. While conventional treatments like dialysis and kidney transplants have proven effective, they come with limitations.

Accessibility, cost, and the need for lifelong intervention are some of the challenges patients and healthcare providers face in managing advanced kidney disease. As such, exploring alternative therapies becomes pivotal in offering comprehensive care and improving outcomes for individuals with kidney disease.

Astragalus (Huang Qi) and Kidney Benefits

Reduction of inflammation and oxidative stress

Astragalus combats inflammation and oxidative stress, key factors in kidney disease progression. Its potent anti-inflammatory properties alleviate kidney tissue burden, while strong antioxidants protect cells and support renal health.

A 2021 study looked at how a compound from Astragalus membranaceous and Angelica sinensis can help treat diabetic kidney disease. They used networking pharmacology and molecular docking techniques to find 142 important targets linked to processes like apoptosis, oxidative stress, inflammation, and insulin resistance.

Results showed that the astragalus-angelica sinensis compound worked well with these targets, and in real-life tests, it improved many aspects of kidney disease in diabetic rats. It lowered their FBG level, increased INS levels, improved kidney functions, reduced urinary proteins, inhibited glycogen buildup, prevented white blood cell infiltration, and stopped excessive collagen growth in kidney tissue.

Support for immune system function

Astragalus is known for its ability to bolster immune system function, making it a valuable asset in kidney health support. Its immunomodulatory properties work to strengthen the body’s defenses, particularly beneficial for individuals with compromised kidney function who may be more susceptible to infections.

A 2017 review analyzed Astragalus membranaceus’ potential in extending lifespan, combating vascular and brain aging, and its anti-cancer properties. According to this study, the widely used TCM herb showed promise in various health aspects. It contains polysaccharides, flavonoids, and saponins, and its extract can boost telomerase activity and possess antioxidant, anti-inflammatory, immunoregulatory, anticancer, and other beneficial effects. Additionally, a specific extract called TA-65 demonstrated age-reversal effects on the immune system.

Furthermore, Astragalus root is one of the main ingredients in Yu Ping Feng San, a famous formula in traditional Chinese medicine (TCM) that was created by the renowned physician Zhu Dan Xi during the Yuan Dynasty (1271-1368). This formula is well-known for its ability to act as a preventive measure against respiratory infections, including the flu and common colds.

Yu Ping Feng San is composed of three main herbs:

1. Huang Qi (Astragalus Root): This herb is known for its immune-boosting properties. It helps strengthen the body’s defensive Qi (Wei Qi), making it more resilient to external pathogens.
2. Bai Zhu (White Atractylodes): Bai Zhu is believed to enhance the function of the spleen and stomach. It aids in digestion and helps the body absorb nutrients, contributing to overall vitality and immunity.
3. Fang Feng (Siler): Fang Feng is known for its ability to dispel wind from the body. In TCM, “wind” is often associated with the invasion of external pathogens. By preventing the penetration of wind, Fang Feng helps to safeguard against illnesses.

Together, these herbs form a powerful combination that reinforces the body’s protective Qi, strengthens the immune system, and establishes a defensive barrier against external pathogens.

Enhancement of blood pressure regulation

Astragalus exhibits promise in regulating blood pressure levels, a critical aspect of kidney health. Its properties contribute to optimal blood flow, aiding in the maintenance of healthy blood pressure and providing an additional layer of support for individuals managing kidney conditions.

In a 2021 study, Astragalus polysaccharide extract (APS) showed promise in protecting against renal damage in hypertensive mice. The study found that APS reduced blood pressure, inflammation, and renal fibrosis in mice induced with hypertension. It also improved renal function by reducing levels of certain markers associated with kidney damage. At the molecular level, APS inhibited the activation of the TGF-β1/ILK signaling pathway, which was heightened in hypertensive mice. These findings suggest that APS may have a beneficial impact on renal dysfunction in hypertensive individuals.

Promotion of overall kidney function and filtration

Astragalus plays a pivotal role in promoting overall kidney function and filtration efficiency. Its ability to enhance blood flow and support optimal filtration rates contributes to the overall health and vitality of the kidneys.

A 2022 study examined the impact of astragalus-containing preparations on kidney function in patients with mild to moderate chronic kidney disease (CKD). They analyzed data from 37 patients who were prescribed these preparations. The results showed a significant improvement in estimated kidney filtration rate after taking astragalus-containing preparations. This improvement was consistent across different age groups, genders, CKD stages, dosages, and durations of use.
