Astragalus
Astragalus membranaceus (Huang Qi)
Traditional Chinese herb used for immune support and longevity, with research on telomere protection.
Astragalus is one of the most important herbs in Traditional Chinese Medicine, used for thousands of years to support immune function and vitality. Modern research has focused on its polysaccharides for immune support and cycloastragenol for potential telomere-lengthening effects. Used for immune resilience and healthy aging.

Top studies from 40+ peer-reviewed papers
Liang H et al. • Renal failure (2025)
“Through rigorous experimental validation, our study demonstrates AS's significant clinical efficacy in managing DN.”
Key Findings:
- Meanwhile, when the treatment duration exceeds 12 weeks, AS demonstrated a significant reduction in fasting blood glucose levels, indicating a time-dependent effect.
- Through rigorous experimental validation, our study demonstrates AS's significant clinical efficacy in managing DN.
- Specifically, AS has been shown to enhance renal function, ameliorate renal fibrosis, and positively influence iron metabolism.
- Despite these promising outcomes, future research with a larger sample size must be conducted to further substantiate these findings.
Tang S et al. • Frontiers in endocrinology (2025)
“TCM has demonstrated considerable effectiveness in managing diabetes.”
Key Findings:
- TCM has demonstrated considerable effectiveness in managing diabetes.
- Through meta-analysis and network pharmacology research, this translational study establishes Level 1a evidence for TCM's antidiabetic efficacy while decoding its systems-level mechanisms.
- The integrated methodology provides a paradigm for evaluating complex herbal interventions in metabolic disorders.
Li Q et al. • Naunyn-Schmiedeberg's archives of pharmacology (2025)
“The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.”
Key Findings:
- No substantial distinctions were noted between the two groups in terms of CD8 + T cell count [MD = -1.74, 95% CI (-4.66, 1.17), P = 0.242].
- Regarding adverse reactions, the incidence of symptoms such as hand-foot numbness and weakness was low, indicating a high safety profile.
- Supplementation with APS can improve treatment outcomes, enhance immune function, and demonstrate a high level of safety in malignant tumor patients, making it a promising option for clinical use.
- However, given the variety of cancer types included in the studies, future research should focus on specific cancer types.© 2025.
Lin YQ et al. • Renal failure (2024)
“The astragalus-RAAS blocker combination treatment is safe and improves outcomes; however, rigorous randomized, large-scale, multi-center, double-blind trials are needed to evaluate its efficacy and safety in stage III DN.”
Key Findings:
- Meanwhile, the latter significantly decreased the urinary microprotein (β2-MG).
- The astragalus-RAAS blocker combination treatment is safe and improves outcomes; however, rigorous randomized, large-scale, multi-center, double-blind trials are needed to evaluate its efficacy and safety in stage III DN.
- Further research warranted to confirm findings
Hong KF et al. • Journal of integrative and complementary medicine (2024)
“PROSPERO REGISTRATION NUMBER CRD42022338491.”
Key Findings:
- The total effective ratio of the OG is more effective than CG (RR = 1.33, 95% CI: 1.26-1.40, P = 0.000), the significant effective ratio (RR = 1.69, 95% CI: 1.48-1.93, P = 0.000).
- Conclusions: Astragalus may provide specific benefits for T2DM patients as an adjuvant treatment.
- Nonetheless, the certainty of the evidence and risk of bias fell short of optimal performance, indicating the need for additional clinical research to ascertain potential effects.
- PROSPERO REGISTRATION NUMBER CRD42022338491.
