What intravenous fluid is best for deficiency of qi and blood?

When intravenous therapy is needed to regulate deficiencies in qi and blood, options such as Shengmai injection, Huangqi injection, Danggui injection, Compound Ejiao Syrup injection, and Bazhen injection are commonly used. A detailed analysis is as follows:

1. **Shengmai Injection**: The main ingredients are red ginseng and Ophiopogon japonicus (Mai Dong). It functions to tonify qi and nourish yin, promote fluid production, and nourish the blood. It is suitable for individuals with deficiency of both qi and yin. It can improve symptoms such as fatigue, dizziness, and dry mouth by replenishing vital energy and nourishing yin fluids, thereby promoting the generation of qi and blood. It is commonly used clinically for regulating constitutionally weak individuals.

2. **Huangqi Injection**: The primary component is Astragalus membranaceus (Huangqi), which has effects of reinforcing qi, uplifting yang, strengthening the exterior, and stopping sweating. It focuses on boosting qi to promote the circulation of qi and blood. It enhances spleen and stomach function, increases energy in those with qi deficiency, and alleviates symptoms such as shortness of breath, reluctance to speak, and excessive sweating, thus providing momentum for blood production.

3. **Danggui Injection**: Mainly composed of Angelica sinensis (Danggui), it excels at nourishing and activating the blood, regulating menstruation, and relieving pain. It is a commonly used intravenous formulation for treating blood deficiency. It nourishes liver blood, improves sallow complexion and dizziness caused by blood deficiency, and simultaneously promotes blood circulation to prevent blood stasis.

4. **Compound Ejiao Syrup Injection**: This formulation combines ingredients such as donkey-hide gelatin (Ajiao), red ginseng, and Rehmannia glutinosa (Shu Di Huang), offering both qi-tonifying and blood-nourishing effects with gentle and long-lasting nourishment. It is suitable for individuals with evident dual deficiency of qi and blood, helping to relieve symptoms such as palpitations, insomnia, mental fatigue, weakness, and pallor, comprehensively replenishing both qi and blood.

5. **Bazhen Injection**: Composed of eight herbs including Codonopsis pilosula (Dangshen), Atractylodes macrocephala (Baizhu), Angelica sinensis (Danggui), and Rehmannia glutinosa (Shu Di Huang), it follows the traditional formula principle of "Bazhen Tang" (Eight Treasures Decoction), achieving a balanced effect of replenishing both qi and blood. It supports both spleen and stomach function and nourishes qi and blood, making it suitable for qi and blood deficiency caused by weakened spleen and stomach function and insufficient production of qi and blood, effectively improving various associated discomforts.

Intravenous therapy should be conducted under the guidance of a qualified physician. Prior to treatment, it is essential to confirm the absence of drug allergies and strictly control the infusion rate and dosage. If symptoms do not improve or adverse reactions occur, the treatment plan should be adjusted promptly. Blind reliance on intravenous infusions should be avoided.
