[0002] Postpartum women often experience significant energy and blood depletion during childbirth, leading to a general state of qi and blood deficiency. Symptoms include pale complexion and weakness in the limbs. From a medical and modern nutritional perspective, scientific and comprehensive replenishment is necessary to accelerate recovery. Compared to traditional chemical supplements, dietary therapy is increasingly popular among postpartum women due to its natural, safe, adaptable, and diverse advantages. Consequently, numerous dietary powders specifically formulated for postpartum women have emerged on the market, primarily containing ingredients like donkey-hide gelatin and red dates—food and medicine homologous. However, these powders still have limitations that restrict their effectiveness. In addition to qi and blood deficiency, postpartum women often experience weakness in their spleen, stomach, and intestines, resulting in impaired digestion and absorption. Even with daily consumption of these powders, achieving adequate replenishment is difficult, as the nutrients are not fully utilized. Summary of the Invention

[0024] Preferably, in step (3), the irradiation dose is 3-5 kGy.

[0025] The beneficial effects of this invention are as follows: This invention uses black sesame seeds, jujube slices, donkey-hide gelatin hydrolysate, angelica, grape seeds, red lotus seeds, carrots, white hyacinth beans, fox nuts, goji berries, chrysanthemum tea powder, black peanuts, cashews, and brown sugar as raw materials to produce a therapeutic powder using general food processing techniques. It establishes for the first time a three-pathway model of "promoting iron absorption - anti-oxidative protection - strengthening the spleen and aiding digestion," with black sesame seeds, donkey-hide gelatin hydrolysate, grape seeds, and white hyacinth beans as core ingredients. This allows postpartum women who consume this therapeutic powder to not only replenish qi and blood but also improve their overall health. For those with weak spleen and stomach, black sesame seeds, rich in iron and vitamin E, provide a foundation for hematopoiesis, nourishing essence and blood. Meanwhile, donkey-hide gelatin enzymatic hydrolysate (donkey-hide gelatin undergoes enzymatic hydrolysis, significantly improving its water solubility and absorbability, allowing it to exert its effects more effectively; furthermore, the combined hydrolysis by alkaline protease and trypsin provides a complementary effect, resulting in better compatibility with other raw materials) promotes hemoglobin synthesis and improves iron utilization, thus nourishing blood and yin. The two complement each other. The ingredients work synergistically to effectively enhance bodily functions and alleviate blood and qi deficiency. Meanwhile, the anthocyanins in grape seeds possess strong antioxidant properties, reducing oxidative damage to red blood cells and directly nourishing, replenishing, and invigorating the blood. White hyacinth beans are high in dietary fiber, promoting intestinal peristalsis, improving spleen and stomach weakness, and offering numerous benefits to the digestive system, enhancing the body's conversion and utilization of nutrients. Furthermore, this invention uses chrysanthemum tea powder and cashew nuts as synergistic ingredients. Chrysanthemum tea powder is rich in phenolic substances, and cashew nuts contain high-quality fats; both can improve metabolism and blood circulation, allowing the technical effects of the aforementioned core ingredients to be fully realized. However, since chrysanthemum is a cold-natured substance, its content in the therapeutic powder should not be excessive, and the extraction time should be carefully controlled during preparation, with 8-12 minutes being optimal. Finally, jujube slices, angelica, and red lotus seeds are used as base ingredients, and through a reasonable and scientific formulation, the therapeutic powder is composed, resulting in excellent nourishing effects.
