Introduction: Mr. Zhang, 68 years old this year, has deep traces of time on his face, and quietly brought many challenges to his body. With the increase in age, coupled with years of accumulated unhealthy habits such as irregular diet, lack of exercise, and occasional indulgence in smoking and alcohol, Mr. Zhang’s health gradually raised red flags.
Recently, he clearly felt that his body was not as good as before, especially his kidney function, which began to show obvious signs of decline. Frequent nocturia, soreness in the waist and knees, and other symptoms made him feel greatly troubled.
After a comprehensive physical examination, the doctor solemnly informed Mr. Zhang that his kidney function was already in need of long-term attention and treatment. In order to alleviate the condition and promote kidney repair and nourishment, the doctor carefully prepared a traditional Chinese medicine prescription for Mr. Zhang, aiming to help him recover his health through the overall concept of Chinese medicine and the principles of dialectical treatment.
However, in this prescription, a Chinese herbal medicine named Astragalus caused great doubt for Mr. Zhang. He vaguely remembered hearing neighbors discussing that although Astragalus is a holy medicine for tonifying qi, it could also burden the kidneys and even cause harm.
This worry weighed heavily on him like a huge boulder, making him strongly resist the prescription issued by the doctor. Mr. Zhang sat at home, tightly holding the prescription in his hand, feeling a mix of emotions.
He both longed to improve his physical condition through treatment and feared worsening the condition due to misuse of medication. After much contemplation, Mr. Zhang decided not to act hastily, but to first search for information on his own, to deeply understand the nature and effects of Astragalus, and whether it really could harm the kidneys as rumored.
Effects and Functions of Astragalus
Immune Regulation
In the fast-paced modern life, the body’s immunity often decreases due to factors such as stress and environmental pollution. The polysaccharides in Astragalus can effectively enhance the activity of immune cells, promote the generation of immune factors, thereby helping the body build a strong defense barrier, reduce the invasion of common diseases such as colds and allergies.
Promoting Cardiovascular Health
Astragalus is rich in flavonoids with antioxidant, anti-inflammatory, and vasodilating properties. It can reduce blood viscosity, promote blood circulation, reduce the risk of blood clot formation. Long-term moderate intake of Astragalus helps maintain stable blood pressure, prevent the occurrence of cardiovascular diseases, and make the heart beat more healthily and vigorously.
Delaying Aging
Astragalus is also a “beauty guru,” its rich nutrients can nourish the skin, promote cell metabolism, reduce damage to the skin from free radicals, thus achieving the effects of delaying aging, reducing fine lines, and brightening the complexion. For modern people pursuing natural beauty and healthy beauty, Astragalus is undoubtedly a natural skincare product with both internal and external benefits.
Supplementing Qi and Invigorating Yang
Astragalus tastes sweet, slightly warm in nature, enters the Spleen and Lung meridians, can supplement Qi, strengthen the Spleen, and boost Qi to invigorate Yang. It is suitable for conditions caused by sinking of Middle Qi leading to visceral prolapse (such as prolapse of the anus, uterine prolapse), as well as situations of Qi deficiency causing weak body, spontaneous sweating, and more.
Dredging Water to Reduce Swelling
Astragalus has the function of enhancing the transformation of the Spleen and Stomach, promoting the transformation of dampness, hence can promote diuresis and eliminate dampness. It is used to treat symptoms such as edema and oliguria caused by Qi deficiency.
Generating Body Fluids and Nourishing Blood
Astragalus can supplement Qi and receive blood, promote blood circulation, thereby playing a role in generating body fluids and nourishing blood. It is suitable for situations of Qi deficiency leading to blood in stool, menorrhagia, etc. Additionally, it also has a regulatory effect on pain, numbness, and conditions like hemiplegia caused by Qi deficiency and blood stasis.
Will long-term consumption of Astragalus water damage the kidneys?
Astragalus, as a shining pearl in the treasure trove of Chinese medicine, has always been regarded as a good product for tonifying Qi and invigorating the middle, widely used in various Chinese medicine prescriptions and daily dietary therapies.
With its sweet and warm nature, being associated with the Spleen and Lung meridians, it not only helps enhance the body’s positive energy and strengthen the body’s resistance but is also often recommended for conditions of physical weakness and loss of appetite.
However, in recent years, the statement “Astragalus harms the kidneys, prolonged consumption of Astragalus water is harmful” circulating in society has made many people skeptical about the consumption of Astragalus.
From a scientific research perspective, there is currently no conclusive evidence that Astragalus itself has direct kidney toxicity. On the contrary, multiple studies, including in-depth explorations by Professor Wang Haiyan of the Nephrology Department of Peking University First Hospital and her team, have revealed the positive role of Astragalus in protecting kidney function.
Astragalus can regulate the immune system, promote microcirculation in the kidneys, help reduce the burden on the kidneys, and even demonstrate certain potential in auxiliary treatment for certain kidney diseases such as chronic nephritis, nephrotic syndrome, etc. Additionally, the diuretic effect of Astragalus also helps excrete excess water and waste from the body, reducing the metabolic pressure on the kidneys.
However, it is important to note that while Astragalus has many benefits, it does not mean that it can be consumed indiscriminately. Traditional Chinese medicine emphasizes “medicinal and food homology, moderation in all things,” and any medication or ingredient may produce adverse reactions when used improperly or inappropriately given the individual’s constitution.
Astragalus is slightly warm and tonifying, and for individuals with actual heat or Yin deficiency and excessive fire, or patients in states of colds with fever, inflammatory infections, excessive consumption of Astragalus may exacerbate the heat in the body, leading to symptoms of agitation, sore throat, flushing, insomnia, elevated blood pressure, and even in certain cases, may worsen the condition.
Therefore, Astragalus, as a traditional Chinese medicinal herb, its benefits to the kidneys are apparent, but it must be used properly based on individual constitution and condition under the guidance of a professional doctor. Regarding the rumor of “Astragalus harming the kidneys,” we should maintain a rational attitude, neither blindly believing nor ignoring it, but rather understanding and utilizing the medicinal value of Astragalus correctly through scientific research and professional guidance.
Though Astragalus is good, how should it be consumed for health?
Moderation is appropriate, excess is harmful
Though Astragalus tonifies, more is not necessarily better. Overconsumption may lead to symptoms of dry-heat and internal heat, especially for those with a constitution tending towards warmth or experiencing symptoms of internal heat, caution should be exercised. It is generally recommended not to exceed 15 grams per day, and adjustment should be made according to individual constitution and doctor’s advice.
Reasonable Combination, Complementary Effects
Astragalus is warm in nature, and single consumption may have unfavorable effects on certain individuals. Therefore, it is often used in combination with other herbs or ingredients, such as soaking it in tea with goji berries, to enhance immunity; or stewing it with Angelica to nourish blood and enhance beauty. Proper combinations not only enhance the efficacy of Astragalus but also reduce side effects.
Timing Awareness, Harmonizing with Nature
According to Traditional Chinese Medicine, the effects of taking medicine at different times vary. Astragalus is generally recommended to be taken in the morning or forenoon when the body’s Yang energy ascends, aiding Astragalus in tonifying Qi and invigorating Yang. In the evening, it is advisable to rest, as excessive tonification might affect sleep quality.
Observation of Reactions, Adjusting Timely
Each individual’s constitution and reaction are unique, so after starting to consume Astragalus, close observation of changes in the body is necessary. If discomfort such as dry mouth or constipation occurs, the dosage should be decreased or discontinued immediately, and professional advice should be sought.
Reminder: These 4 Chinese Herbal Medicines Are the Real Kidney Damagers
Guanmutong
Guanmutong, this ancient and common Chinese medicinal herb, also known as Aristolochia, has a long history and wide application in the field of traditional Chinese medicine. However, its content of aristolochic acid has become a focus of attention in the medical field in recent years. Aristolochic acid, a naturally occurring chemical substance, has been found through in-depth research to have potential kidney toxicity, gradually eroding kidney tubules and interstitial tissues, leading to a series of complex pathological changes, ultimately resulting in impaired kidney function, and may even evolve into irreversible kidney failure.
In view of this, extreme caution must be exercised in the use of Guanmutong and related Chinese medicinal preparations. Patients and the public should fully recognize its potential risks, avoid long-term excessive use to prevent unknowingly damaging kidney health.
At the same time, in clinical use, healthcare professionals need to strictly adhere to the indications for using Guanmutong, accurately control the dose and course of treatment, adjust the treatment plan as needed based on the patient’s specific conditions, and monitor the changes in kidney function closely during treatment to ensure the safe and effective use of medication. In short, the scientific and reasonable use of Guanmutong is an essential part of maintaining human health and preventing drug-induced kidney damage.
Leigongteng
Leigongteng, this Chinese medicine with a long history, occupies an important position in the field of traditional Chinese medicine due to its significant anti-inflammatory and immunosuppressive properties, especially in the treatment of stubborn rheumatoid arthritis, ankylosing spondylitis, and some stubborn skin diseases. However, the dual nature of its medicinal effects should not be overlooked: the specific active ingredients in Leigongteng can pose a potential threat to the body, especially the renal system, while exerting therapeutic effects.
Long-term and excessive use of Leigongteng may gradually accumulate harmful components, causing irreversible damage to the kidneys. These components can induce apoptosis and necrosis of renal tubular epithelial cells, promote fibrotic changes in the interstitial region, thereby destroying normal kidney structure and function, affecting urine production and excretion, ultimately leading to decreased kidney function and even failure.
Therefore, in clinical application, doctors need to strictly control the indications for using Leigongteng, accurately control the dosage and course of administration, and closely monitor the patient’s kidney function indicators, detect and deal with possible kidney damage in a timely manner, ensuring the safe and effective use of medication for patients.
Cang’erzi
As a traditional Chinese medicinal herb, Cang’erzi occupies an important position in traditional Chinese medicine theories due to its unique dispersing ability to dispel wind cold, unblock the nasal passages, and is commonly used in formulas to relieve initial cold symptoms and discomfort caused by rhinitis. However, although it has high medicinal value, it also comes with certain safety risks.
Studies have shown that some complex chemical components in Cang’erzi may under specific conditions or in interaction with certain medications or chemicals, exhibit potential harm to the kidneys. These harmful substances may silently damage renal tubular epithelial cells, interfere with normal physiological function of the kidneys, and thereby lead to severe issues such as decreased kidney function.
Given this, patients must raise vigilance when selecting Cang’erzi or Chinese medicinal products containing its components, avoiding blind combinations or excessive use. More importantly, it is crucial to have a professional TCM physician guide and scientifically formulate treatment plans according to individual constitution, conditions, and medication history, ensuring the effective utilization of Cang’erzi’s therapeutic advantages while effectively mitigating the risk of kidney damage it may carry.
Zhusha
Zhusha, this ancient Chinese medicinal herb, due to its unique calming and detoxifying effects, is commonly used in traditional Chinese medicine to treat symptoms of insomnia, palpitations, and restlessness. However, behind Zhusha’s miraculous therapeutic effects lies an essential safety hazard that cannot be ignored. One of its main components, mercuric sulfide, in the complex biochemical environment of the human body, may gradually transform into toxic mercury ions.
These mercury ions not only disturb the nervous system but may also directly damage the kidneys, affecting filtration and excretion function. Prolonged and excessive consumption of Zhusha or indiscriminate use of Chinese medicinal preparations containing Zhusha components, without professional guidance, may significantly burden the kidneys, eventually leading to progressive decline in kidney function and even inducing serious conditions such as tubulointerstitial nephritis.
Therefore, when choosing Zhusha as a treatment method, patients must strictly follow medical advice, control the dosage and course of administration accurately, undergo regular kidney function assessments, ensuring the enjoyment of Zhusha’s therapeutic effects while effectively preventing potential kidney damage risks.
There is an art to taking Chinese medicine, which is the best time to drink for optimal effectiveness? Generally, these 3 time periods are best
Taking Chinese Medicine on an Empty Stomach
This is particularly suitable for medications classified as tonifying, deworming, or treating diseases of the blood vessels in the limbs. At this time, the stomach and duodenum have no food, allowing the medication to quickly enter the small intestine for absorption without mixing with food, thereby exerting its effect. However, if a patient has weak Spleen and Stomach function, taking medication on an empty stomach may cause discomfort and should be adjusted to after meals.
Half an Hour Before or After a Meal
Generally, medicines for tonifying the Spleen and Stomach or aiding digestion should be taken before meals to facilitate digestion; most medicines, especially those that may irritate the stomach and intestines, should be taken half an hour after a meal to reduce stimulation of the stomach mucosa and protect the Spleen and Stomach.
Taking Medicine Before Bedtime
This is particularly suitable for sedative and hypnotic drugs or medications for soothing bowel movements. At this time, the body is in a state of rest, and after the medication is absorbed, it can better exert its therapeutic effect, avoiding inconveniences that daytime medication may bring. However, after taking the medicine, it is advisable to engage in light activities before going to sleep to prevent the medication from lingering in the esophagus, causing discomfort.
