Introduction

Under normal circumstances, soaking Codonopsis, Astragalus, and Ophiopogon in water has functions such as replenishing qi and nourishing yin, strengthening the spleen, and benefiting the lungs. However, it is contraindicated for individuals with damp-heat constitution and should be used with caution. Codonopsis and Astragalus are particularly effective for boosting qi, while Ophiopogon mainly nourishes yin. When these three herbs are combined in a soak, they help address deficiencies in both qi and yin, alleviating symptoms such as fatigue and dry mouth caused by dual deficiency of qi and yin. This preparation is suitable for consumption by individuals with weak constitutions.

Under normal circumstances, soaking Codonopsis, Astragalus, and Ophiopogon in water has functions such as tonifying qi and nourishing yin, strengthening the spleen and benefiting the lungs. However, there are also contraindications—for example, those with damp-heat constitutions should use it cautiously. Detailed analysis is as follows:

I. Functions

1. Tonifies Qi and Nourishes Yin: Codonopsis and Astragalus are effective for boosting qi, while Ophiopogon focuses on nourishing yin. When used together in infusion, they help replenish deficiencies of both qi and yin, alleviating symptoms such as fatigue and dry mouth caused by dual deficiency of qi and yin. This makes the combination suitable for individuals with weak constitutions.

2. Strengthens the Spleen and Benefits the Lungs: Both Codonopsis and Astragalus can strengthen the spleen and benefit the lungs. They enhance the digestive and transforming functions of the spleen and stomach and nourish the lungs, helping relieve poor appetite due to spleen deficiency and shortness of breath or coughing due to lung deficiency.

3. Promotes Fluid Production and Relieves Thirst: Ophiopogon moistens dryness and promotes body fluid production. Combined with Codonopsis and Astragalus, it helps nourish bodily fluids and improves symptoms such as dry mouth, sore throat, and throat dryness. It is especially suitable for individuals in dry environments or those with yin-deficient constitutions.

4. Calms the Heart and Improves Sleep: Ophiopogon clears heat from the heart and relieves irritability, while Codonopsis and Astragalus tonify qi and blood. Together, they help alleviate insomnia, frequent dreams, palpitations, and restlessness caused by insufficient qi and blood or hyperactivity of fire due to yin deficiency, thereby improving sleep quality.

5. Boosts Qi and Nourishes Blood: Codonopsis and Astragalus tonify qi, which in turn promotes blood production, while Ophiopogon nourishes yin and blood. Used together, they support the generation of qi and blood, improving symptoms such as pallor, dizziness, and fatigue due to deficiency of qi and blood, thus enhancing overall physical condition.

II. Contraindications

1. Use with Caution in Damp-Heat Constitutions: Codonopsis and Astragalus are warm in nature and sweet in taste. Excessive consumption may exacerbate internal damp-heat, leading to worsening symptoms such as yellow, greasy tongue coating, bitter taste in the mouth, and sticky stools. Individuals with such constitutions should use this remedy cautiously.

2. Avoid During Cold or Fever: All three herbs are tonic in nature. Consuming them during a cold or fever may hinder the expulsion of external pathogens, potentially worsening fever and delaying recovery. Consumption should be suspended until symptoms resolve.

3. Use with Caution in Cases of Abdominal Distension and Qi Stagnation: Codonopsis and Astragalus have a relatively rich and sticky texture that may impede the flow of qi, aggravating symptoms such as bloating and belching caused by qi stagnation. Individuals experiencing these symptoms should avoid or reduce intake.

4. Avoid in Cough Due to Phlegm-Heat: Although Ophiopogon can moisten dryness, the warming properties of Codonopsis and Astragalus may intensify phlegm-heat, worsening cough and sputum production. Individuals with phlegm-heat conditions should not consume this preparation.

5. Use with Caution in Excess Conditions: For individuals with strong constitutions and no signs of deficiency, consuming this tonic may lead to excessive internal heat, restlessness, or other discomforts. Such individuals do not require this remedy, as unnecessary use may disrupt the body's balance.

Consumption of Codonopsis, Astragalus, and Ophiopogon infusion should be adjusted according to individual constitution; blind use should be avoided. It is recommended to control dosage, avoid long-term or excessive consumption, maintain a light diet, and follow regular作息 (daily routines). If discomfort occurs after consumption, discontinue immediately and consult a qualified healthcare provider promptly.
