The efficacy of泡 water with Gastrodia and Astragalus
Generally, when Gastrodia elata (Tianma) and Astragalus membranaceus (Huangqi) are steeped together in hot water for consumption, the main benefits include replenishing qi and uplifting yang energy, enhancing alertness, promoting blood circulation to remove blood stasis, boosting immunity, and regulating blood pressure. Detailed explanations are as follows:

1. Replenishing Qi and Uplifting Yang Energy: Astragalus is a commonly used herbal medicine for replenishing qi. When combined with Gastrodia for steeping, it enhances physical strength and alleviates fatigue caused by qi deficiency. The sweet taste and slightly warm nature of Astragalus, which enters the spleen and lung meridians, help to boost the body's yang energy.
2. Enhancing Alertness: Gastrodia contains gastrodin, which helps improve sleep quality and thereby indirectly combats fatigue. Astragalus promotes energy production and enhances physical vitality. The combination of these two herbs can improve mental alertness and reduce feelings of fatigue.
3. Promoting Blood Circulation and Removing Blood Stasis: Steeping Astragalus and Gastrodia together also promotes blood circulation, helping to relieve limb pain and improve poor circulation. These effects are primarily related to the blood-activating and stasis-resolving properties of Gastrodia.
4. Boosting Immunity: Polysaccharides found in Astragalus have immune-regulating properties and can increase white blood cell count, thereby enhancing the body's resistance. Consuming Gastrodia and Astragalus together helps improve overall immunity and reduce the incidence of illness.
5. Regulating Blood Pressure: Both Gastrodia and Astragalus have certain blood pressure-regulating effects. Drinking an appropriate amount of Gastrodia-Astragalus infusion can help stabilize blood pressure and may serve as an adjunct treatment for patients with hypertension.
If one intends to consume Gastrodia and Astragalus tea, it should be done under the guidance of a physician to ensure safety. Additionally, it should not be consumed concurrently with certain other herbs such as Veratrum (Lilu) or Myrrha (Wulingzhi) to avoid potential interactions that might reduce efficacy or cause adverse reactions.
