Introduction
Dendrobium (Shihu) and Astragalus (Huangqi) steeped in water generally has functions including anti-fatigue, invigorating qi to consolidate the exterior, nourishing yin to clear heat, benefiting the stomach and promoting body fluid production, as well as relieving dampness and reducing swelling. However, the consumption of Dendrobium and Astragalus water should be moderate to avoid excessive intake that may lead to adverse reactions such as heatiness or gastrointestinal discomfort. Additionally, during consumption, it is advisable to avoid eating spicy and irritating foods, such as chili peppers and Sichuan peppercorns, to prevent interference with the herbal efficacy.
Dendrobium and Astragalus tea typically offers benefits such as anti-fatigue effects, invigorating qi to strengthen the body's defenses, nourishing yin to clear heat, promoting gastric fluid production, and relieving dampness and swelling. Detailed explanations are as follows:
1. Anti-fatigue
Both Dendrobium and Astragalus contain abundant bioactive components, such as amino acids and trace elements, which can provide essential nutrients to the body, alleviate fatigue, and improve work efficiency and quality of life.
2. Invigorating Qi and Strengthening the Body's Defenses
Astragalus is known as a superior herb for replenishing qi, especially effective in strengthening the qi of the lungs and spleen, reinforcing the body's surface to stop sweating. For individuals with qi deficiency and weak constitution who are prone to colds, long-term consumption of Dendrobium and Astragalus tea can enhance physical strength and reduce the risk of illness.
3. Nourishing Yin and Clearing Heat
Dendrobium has a slightly cold nature and sweet taste, excelling in nourishing yin and clearing heat. It is suitable for symptoms such as yin deficiency with fire hyperactivity, dry mouth and throat. Although Astragalus mainly functions to replenish qi, when combined with Dendrobium, its warming and nourishing properties can balance Dendrobium's cold nature, making the overall formulation mild. This combination nourishes yin without excessive coldness, making it suitable for a broader population.
4. Promoting Gastric Fluid Production
Dendrobium is a herb that promotes gastric fluid production. It effectively inhibits Helicobacter pylori, a common pathogen in gastrointestinal diseases, and helps treat conditions such as atrophic gastritis and superficial gastritis. When combined with Astragalus, it enhances gastrointestinal function and improves symptoms such as poor appetite, abdominal distension, and diarrhea.
5. Promoting Dampness Drainage and Reducing Swelling
Both Dendrobium and Astragalus help promote the elimination of dampness from the body. Astragalus can replenish qi and promote diuresis, aiding in treating edema and reduced urine output caused by qi deficiency. It also serves as an adjunct treatment for edema associated with chronic nephritis and nephrotic syndrome. Dendrobium helps alleviate symptoms of limb swelling and pain. Together, they more effectively promote dampness drainage and reduce swelling.
However, Dendrobium and Astragalus tea should be consumed in moderation to avoid excessive intake that may lead to adverse reactions such as heatiness or gastrointestinal discomfort. Additionally, during consumption, it is advisable to avoid eating spicy and irritating foods, such as chili peppers and Sichuan peppercorns, as they may interfere with the herbal effects.
