Astragalus is a revered herb in Traditional Chinese Medicine (TCM), lauded for centuries for its adaptogenic and immune-supporting properties. Available in forms like organic astragalus extract powder, organic astragalus root powder, and organic astragalus root slices, it’s gaining popularity in the Western world for its potential health benefits. While generally considered safe for most people, it’s natural to wonder: What are the negative side effects of astragalus?
Understanding potential considerations is key to incorporating any supplement safely into your routine. Here’s a look at the known side effects and important precautions.
Generally Well-Tolerated, but Mild Effects Possible
For the vast majority of individuals, astragalus, particularly when consumed within recommended dosages, is well-tolerated. When side effects do occur, they are typically mild and may include:
- Mild Digestive Upset: Some people might experience minor stomach discomfort, bloating, or diarrhea, especially when first introducing astragalus or if taking very high doses. Starting with a lower dose and gradually increasing can help mitigate this.
- Drowsiness: Although less common, a small number of users have reported feelings of drowsiness. If this occurs, it might be best to take astragalus in the evening.
Important Interactions and Contraindications
The most significant considerations for astragalus involve its interactions with certain medications and its effects on specific health conditions:
- Interactions with Immunosuppressant Drugs:
- The Drawback: Astragalus is known for its immune-boosting properties. This is its great strength, but it becomes a drawback if you are taking medications designed to suppress the immune system. This includes drugs used after organ transplants (e.g., cyclosporine, corticosteroids) or for autoimmune diseases (e.g., azathioprine, prednisone).
- Why: Astragalus could potentially counteract the effects of these life-saving medications, making them less effective and potentially leading to organ rejection or flare-ups of autoimmune conditions.
- Action: If you are on any immunosuppressant therapy, avoid astragalus entirely unless specifically advised and monitored by your healthcare provider.
- Impact on Autoimmune Diseases:
- The Concern: Because astragalus stimulates the immune system, there’s a theoretical concern that it could exacerbate symptoms in individuals with autoimmune diseases such as rheumatoid arthritis, lupus, multiple sclerosis, or Hashimoto’s thyroiditis.
- The Science: While human studies are limited and evidence isn’t conclusive, the general advice is to exercise caution or avoid astragalus if you have an autoimmune condition. Always consult your doctor before using it.
- Blood Sugar and Blood Pressure Medications:
- The Potential: Some research suggests astragalus might have mild effects on blood sugar levels and blood pressure.
- The Drawback: If you are already taking medications for diabetes or high blood pressure, combining them with astragalus could potentially lead to blood sugar or blood pressure dropping too low.
- Action: If on these medications, monitor your levels closely and discuss astragalus supplementation with your doctor to ensure there are no adverse interactions.
- Pregnancy and Breastfeeding:
- Lack of Data: There is insufficient reliable information about the safety of astragalus during pregnancy and breastfeeding.
- Action: As a precautionary measure, it is generally recommended to avoid astragalus if you are pregnant or breastfeeding.
Choosing Your Astragalus Product
Whether you choose organic astragalus extract powder (a concentrated form often used in supplements), organic astragalus root powder (the whole ground root, versatile for blending), or organic astragalus root slices (ideal for making teas or soups), ensure you opt for organic sources. This minimizes exposure to pesticides and ensures a purer product.
In conclusion, while astragalus is widely used and typically safe, its immune-modulating properties mean it’s not suitable for everyone, particularly those on immunosuppressant drugs or with autoimmune conditions. Always prioritize open communication with your healthcare provider before starting any new supplement, especially if you have underlying health conditions or are taking medications.
