What parts of this plant are used medicinally?

This plant Astragalus sinicus is primarily utilized in traditional medicine for its medicinal properties found in the roots, leaves, seeds, stem, and nodules. The roots are the most significant part used to formulate tonics that enhance immune function and vital energy. Medicinally, the leaves can be processed to treat various inflammatory conditions or digestive issues. Some preparations also incorporate the seeds and stem to address specific systemic ailments. Even the nodules on the roots are sometimes studied or included in traditional decoctions for their unique biological contributions.

According to a study published by "Plant physiology", the leaves, stems, and roots of Astragalus sinicus were used to detect the ASA2 transcript and high free Trp. The expression of the feedback-insensitive ASA2 resulted in a 1.3- to 5.5-fold increase in free Trp. These hairy root lines transformed with 35S-ASA2 grew in concentrations of up to 100 microM 5MT. In contrast, the controls were completely inhibited by 15 microM 5MT.

What are the pharmacological activities of Astragalus sinicus?

This plant has significant pharmacological activities including potent antitumor activity, estrogenic activity, and various immunomodulatory effects. Its antitumor properties are primarily driven by polysaccharides that inhibit the proliferation of cancer cells and induce apoptosis. Additionally, the plant exhibits estrogenic activity, which allows its compounds to interact with estrogen receptors in the body. These biochemical actions contribute to its traditional use in treating inflammatory conditions and boosting the immune system. Research continues to explore how these specific bioactive components can be utilized for targeted therapeutic applications.

According to a study published by "Japanese journal of pharmacology", the herb A. capillaris was examined for its effects on Meth A-DTH. This herb augmented the Meth A-DTH 10 days after the primary tumor transplantation. Unlike other herbs studied, A. capillaris did not prevent the decay of the response on the 20th day. The study suggests that A. capillaris shows antitumor activity mainly through a direct cytotoxicity, although it might have certain components to enhance Meth A-DTH. None of the herbs examined affected the PC-DTH.

The primary pharmacological activities of this plant are shown in the list below.

  • antitumor activity
  • estrogenic activity
Evidence Level: ★★★☆☆

What medicinal compounds this plant contains?

This plant contains a diverse range of medicinal compounds including C18:4 fatty acid, Trp, total flavone, and the essential amino acid tryptophan. The presence of total flavone provides significant antioxidant properties that support cellular health and reduce inflammation. Additionally, the specific fatty acid C18:4 contributes to the plant's unique nutritional profile and biological activity. The amino acid components, identified as Trp and more specifically as tryptophan, play a vital role in regulating various physiological functions within the body. Together, these chemical constituents contribute to the therapeutic potential of Astragalus sinicus in traditional and modern medicine.

According to a study published by "Molecular microbiology", three strains of Mesorhizobium huakuii act as symbionts of Astragalus sinicus. These strains produce major Nod factors that are pentameric lipochitooligosaccharides. These compounds are O-sulphated and partially N-glycolylated at the reducing end. Additionally, they are N-acylated at the non-reducing end by a C18:4 fatty acid.

The primary medicinal compounds of this plant are shown in the list below.

  • C18:4 fatty acid
  • Trp
  • total flavone
  • tryptophan

What side effects this plant can have?

This plant can cause serious health complications including potential abortion if consumed in large quantities by pregnant women. The pharmacological properties of Astragalus sinicus may influence hormonal balance or uterine contractions in certain biological contexts. Due to these risks, individuals who are pregnant or nursing should strictly avoid using this plant for medicinal purposes. Consult a medical professional before incorporating this species into any dietary regimen to prevent reproductive harm. Careful monitoring is essential because the specific potency of the plant can vary significantly between different harvests.

According to a study published by "Biochimica et biophysica acta", the proteins trichosanthin, alpha-momorcharin, and beta-momorcharin are confirmed to be abortifacient. The ultraviolet spectra of these proteins were analyzed in the range of 188-250 nm and remained pH-independent between pH 5 and 9. All three proteins contained approximately 30% helix, whereas trichosanthin showed 39% helix in an X-ray diffraction study. The proteins also contained 40-60% beta-sheets but possessed no beta-turns. The addition of 20 mM sodium dodecyl sulfate nearly doubled the helicity of beta-momorcharin at the expense of its beta-sheets.

The main side effects this plant can have are shown in the list below.

  • abortion
