Astragalus Standardized Extract
Also known as: Astragalus, Huang Qi, *Astragalus membranaceus*
Overview
Astragalus is a plant-based supplement derived from the roots of *Astragalus membranaceus*, predominantly utilized in traditional Chinese medicine. Known for its immune-enhancing and fatigue-reducing properties, it contains key bioactive compounds including polysaccharides, flavonoids, and saponins. The current research regarding Astragalus is expanding, focusing on its role in immunomodulation and its potential as a supportive treatment during chemotherapy. Despite emerging evidence, studies often lack rigorous design, necessitating further high-quality trials to solidify the understanding of its efficacy. Common forms for consumption include capsules and tablets, making it accessible for various populations aiming to improve their health outcomes.
Benefits
Astragalus may provide several evidence-based benefits, particularly in enhancing immune function and alleviating cancer-related fatigue. Research indicates that Astragalus-containing prescriptions can lead to significant improvements in tumor response during chemotherapy, as evidenced by a risk ratio of 1.25 in cervical cancer studies. Moreover, populations experiencing chronic fatigue, especially those undergoing cancer treatments, are likely to experience notable benefits. However, comprehensive meta-analyses are still needed to establish definitive conclusions regarding its effectiveness across different conditions.
How it works
The primary mechanism of action for Astragalus involves the modulation of immune function through its various bioactive compounds, particularly polysaccharides. These compounds are believed to enhance systemic immune responses by interacting with immune cells and potentially affecting inflammation pathways. Although specific molecular targets of Astragalus remain inadequately defined, it is suggested that it positively influences immune pathways to promote overall health and resilience, especially during periods of stress, such as illness.
Side effects
Astragalus is generally considered safe for most individuals when used appropriately; however, it can cause some side effects. Commonly reported adverse effects include gastrointestinal upset, occurring in more than 5% of users. Allergic reactions, though rare (1-5%), may also happen. Serious adverse effects are uncommon (<1%) but can include interactions with certain medications. Caution is advised for individuals taking immunosuppressants or blood thinners due to potential drug interactions. It is important for those with autoimmune diseases to avoid its use without medical supervision, and pregnant or breastfeeding women should consult a healthcare provider prior to use to mitigate any risks.
Dosage
The minimum effective dose of Astragalus typically starts at 500 mg per day, with optimal dosage ranges between 500 mg and 2 grams daily. The maximum safe dose is not well established, but doses above 2 grams are infrequently studied in clinical trials. It is recommended to take Astragalus with meals to reduce the risk of gastrointestinal upset. Common forms for consumption include capsules and tablets, which may vary in bioavailability; hence, optimal dosing should consider the specific delivery system used.
