The combination of Astragalus, Radix et Rhizoma Ginseng and Fructus Jujubae belongs to the typical direction of combining Qi and Blood together. 1. Astragalus and Radix et Rhizoma Ginseng are both qi tonic drugs, and are relatively effective in tonifying qi, capable of tonifying the center and benefiting qi (treating qi deficiency by tonifying the spleen). However, Radix et Rhizoma Ginseng should not be used together with Radix quinquefolium and Radix et Rhizoma Ginseng; Radix Astragali should not be used when the surface is solid and evil, when sores and ulcers are at the beginning of their development, or when heat and toxins are still prevalent after ulceration. 2. Red jujube is a typical blood tonic, also has the effect of tonifying the middle Jiao, nourishing the blood and calming the mind (through nourishing the blood to stabilize the mind and soothe the emotions). However, it should be taken with caution or contraindicated in cases of dampness, phlegm condensation, food stagnation, worms accumulation and dental diseases. 3. The use of the three herbs together corresponds to the Chinese medical theory that “blood is the mother of qi and qi is the commander of blood (qi commands the operation of blood)”. In other words, qi and blood are symbiotic, and the operation of qi and blood should be regulated from the perspective of tonifying qi and nourishing blood at the same time. Common Chinese medicine prescriptions, such as Angelica Soup and Eight Treasures Soup, are based on this theory. Medications should be taken under the guidance of a professional physician to avoid adverse effects.
