It is important to note that while it is commonly used in traditional medicine, its long-term safety has not been fully established, and high doses may lead to more severe adverse effects. Astragalus gummifer may interact with certain medications, including immunosuppressants and anticoagulants, potentially increasing the risk of bleeding or affecting immune response. Special populations, such as pregnant or breastfeeding women, should avoid its use due to insufficient safety data, and individuals with chronic illnesses should consult a healthcare provider before use.

For safe use, it is recommended to follow recommended dosages, consult a healthcare professional, and discontinue use if any adverse effects occur.

Growing, Harvesting and Storage

Astragalus gummifer grows best in well-drained, loamy soil with a slightly alkaline pH, thriving in full sun to partial shade and requiring moderate watering to maintain consistent moisture without waterlogging.

It is a hardy perennial that benefits from regular weeding and occasional fertilization with a balanced organic fertilizer to promote healthy growth. The best time to harvest astragalus gummifer is in late summer to early autumn, when the roots are most potent, using a spade or trowel to carefully dig up the entire plant to avoid damaging the roots. After harvesting, the roots should be washed, cut into pieces, and dried in a cool, dark, and well-ventilated area to preserve their potency and prevent mold.

For long-term storage, dried astragalus should be kept in airtight containers in a cool, dry place or refrigerated to maintain its medicinal properties and extend its shelf life.
