Astragalus root, also known as "huang qi" or milkvetch, has been revered in Traditional Chinese Medicine (TCM) for centuries. Known for its powerful immune-boosting and anti-inflammatory properties, astragalus is often used to promote longevity, improve heart and kidney health, and combat chronic illnesses. Today, modern research supports many of these traditional uses and highlights its potential role in managing diabetes, alleviating chemotherapy side effects, and improving overall vitality.

This article explores the health benefits of astragalus, its role in preventing diseases, and how incorporating this ancient herb into your daily diet can support a healthier lifestyle.

What Is Astragalus Root?

Astragalus is a perennial herb that grows in parts of China, Mongolia, and Korea. With over 2,000 species, Astragalus membranaceus and Astragalus mongholicus are the most commonly used in herbal medicine.

Traditionally, the root of the plant is processed into capsules, teas, powders, and liquid extracts. In hospital settings, astragalus is sometimes administered via IV for specific treatments. The active compounds in the root—such as saponins, flavonoids, and polysaccharides—are believed to offer a range of health benefits, from improving immune function to reducing inflammation.

In Traditional Chinese Medicine, astragalus is considered an adaptogen, meaning it helps the body resist physical, emotional, and environmental stressors.

Health Benefits of Astragalus

1. Boosts the Immune System

One of astragalus’s most well-known benefits is its ability to strengthen the immune system. The herb promotes the production of white blood cells, which play a crucial role in defending the body against infections.

In animal studies, astragalus extract has shown the ability to fight bacterial and viral infections. It may even reduce the frequency and severity of the common cold. Some early human studies suggest that astragalus could be helpful for liver infections and respiratory issues, though more research is needed.

2. Improves Heart Health

Astragalus has been shown to improve heart function by increasing blood flow and reducing inflammation in heart tissues. It may benefit those with conditions like congestive heart failure, where the heart struggles to pump blood efficiently.

In several clinical studies, patients with heart failure who received astragalus along with conventional treatment experienced improved heart function and reduced symptoms compared to those on standard treatments alone.

However, not all studies have shown consistent results, so it’s essential to consult with a healthcare provider before using astragalus for heart-related conditions.

3. Alleviates Chemotherapy Side Effects

Cancer patients undergoing chemotherapy often experience debilitating side effects like nausea, vomiting, and fatigue. Astragalus may help reduce these symptoms and improve the patient’s quality of life.

In one clinical trial, patients receiving astragalus intravenously experienced a significant reduction in nausea, vomiting, and diarrhea compared to those who did not. Additionally, astragalus appeared to combat chemotherapy-induced fatigue, particularly during the early stages of treatment.

4. Helps Control Blood Sugar Levels

For individuals with type 2 diabetes, astragalus can be a valuable tool for managing blood sugar. The active compounds in astragalus improve insulin sensitivity and sugar metabolism, helping to reduce fasting and post-meal blood sugar levels.

In studies conducted on diabetic patients, taking 40–60 grams of astragalus daily for four months resulted in improved blood sugar control and even led to modest weight loss in some cases.

5. Supports Kidney Health

Astragalus is widely used to improve kidney function, especially in individuals with chronic kidney disease (CKD). It may reduce proteinuria, a condition in which excessive protein is found in the urine, indicating kidney damage.

Studies have shown that taking 7.5–15 grams of astragalus daily for several months can reduce the risk of infections in people with nephrotic syndrome, a kidney disorder. This suggests that astragalus not only supports kidney health but also helps prevent complications.

Other Potential Health Benefits

Besides its role in boosting immunity, heart health, and kidney function, astragalus may offer additional benefits:

• Relieves Chronic Fatigue: When combined with other herbs, astragalus may reduce tiredness and improve energy levels in people with chronic fatigue syndrome.
• Reduces Seasonal Allergy Symptoms: Taking astragalus supplements may help reduce sneezing, runny nose, and other allergy symptoms.
• Possesses Anticancer Properties: In test-tube studies, astragalus has been shown to trigger apoptosis (programmed cell death) in cancer cells. However, more human studies are needed.
• May Slow Autoimmune Diseases: Early studies suggest that astragalus may help slow the progression of autoimmune diseases like multiple sclerosis (MS).

Indian Diet Tips for Integrating Astragalus

Incorporating astragalus into an Indian diet can be seamless. Here are some practical ways to use it:

• Astragalus Tea: Brew astragalus root with ginger and tulsi (holy basil) for a powerful immune-boosting tea.
• Powder Form: Add a small amount of astragalus powder to smoothies or sprinkle it into dals, soups, or curries.
• Herbal Decoctions: Boil astragalus with other herbs like ashwagandha and turmeric for a traditional remedy to improve strength and vitality.
• Astragalus-Infused Kadha: Prepare a kadha (herbal decoction) with astragalus, cinnamon, black pepper, and honey to support respiratory health during seasonal changes.

Diet’s Role in Preventing Diseases

A balanced diet plays a crucial role in preventing and managing chronic diseases. Consuming nutrient-dense foods can help regulate blood sugar, reduce inflammation, and boost immune health.

In the context of an Indian diet, focus on:

• Whole Grains: Brown rice, millet, and quinoa provide sustained energy and help manage blood sugar.
• Fresh Vegetables and Fruits: Include a variety of colorful vegetables and fruits for antioxidants and essential nutrients.
• Legumes and Pulses: Rich in protein and fiber, they help support kidney function and heart health.
• Healthy Fats: Use cold-pressed oils like coconut oil or mustard oil, and include nuts and seeds.
• Herbs and Spices: Turmeric, ginger, cumin, and coriander offer anti-inflammatory properties and improve digestion.

Integrating superfoods like astragalus into a balanced diet can further enhance these benefits, especially for individuals dealing with chronic fatigue, kidney issues, or diabetes.

Side Effects and Precautions

For most people, astragalus is safe and well-tolerated. However, some may experience mild side effects such as rash, itching, nausea, or diarrhea.

Avoid astragalus if:

• Pregnant or Breastfeeding: There’s insufficient evidence about its safety during pregnancy.
• On Immunosuppressants: Astragalus may interfere with these medications by increasing immune activity.
• Diabetes or Blood Pressure Issues: Since astragalus affects blood sugar and blood pressure, monitor your levels closely.

Always consult a healthcare provider before starting any herbal supplement, especially if you’re on medication.

Dosage Recommendations

The dosage of astragalus depends on the form and intended use:

• Congestive Heart Failure: 2–7.5 grams of powdered astragalus twice daily for up to 30 days.
• Blood Sugar Control: 40–60 grams as a decoction daily for up to four months.
• Kidney Disease: 7.5–15 grams twice daily for three to six months.
• Chronic Fatigue: 30 grams combined with other herbs in a decoction.
• Seasonal Allergies: Two 80-mg capsules twice daily for six weeks.

In Traditional Chinese Medicine, astragalus is rarely used alone and is often part of a customized herbal formula tailored to the individual’s needs.

Conclusion

Astragalus is a powerful herb with a long history of promoting health and longevity. It may boost the immune system, protect the heart and kidneys, and help manage chronic conditions like diabetes and fatigue.

While more research is needed to confirm some of its benefits, astragalus remains a promising addition to any wellness routine. However, it’s essential to consult with your healthcare provider before starting astragalus, especially if you have underlying health conditions or take medications.

By combining ancient remedies with modern knowledge, we can embrace a holistic approach to health—one rooted in balance, prevention, and the healing power of nature.
