This invention discloses a method for processing the traditional Chinese medicine Pinellia ternata. The method involves processing the raw Pinellia ternata in a phosphate solution under sealed conditions, followed by slicing into thick pieces and drying to obtain the processed product. The medicinal material is Pinellia ternata or Arisaema heterophyllum. The method of this invention uses phosphate solution to soak Pinellia ternata, which significantly reduces its irritant properties. Toxicological experiments have shown that the processed Pinellia ternata is non-irritating and does not cause a numbing sensation on the tongue. This invention does not use alum, thus avoiding the use of residual Al from alum as a processing excipient in pharmacopoeia methods. 3+ The toxicity to the human nervous system is minimal, ensuring safe and effective clinical use. Compared with traditional processing methods, phosphate-processed Pinellia ternata has the advantages of quantifiable process indicators, simple operation, and no introduction of hazards. It provides a reference for the processing technology of phosphate-processed Pinellia ternata, lays the foundation for the quality stability of phosphate-processed Pinellia ternata, and ensures the safety and efficacy of traditional Chinese medicine.

This invention relates to the field of vehicle technology, specifically providing a vehicle charging system and a vehicle, aiming to solve the problem of how to safely and effectively use charging facilities when the voltage levels of the power battery and the charging facility are mismatched. The vehicle charging system of this invention may include a voltage conversion device, a charging port capacitor, a power distribution device, and a charging control device. The charging control device can control the power battery, voltage conversion device, power distribution device, and charging port capacitor to form different conduction circuits, control the power battery to pre-charge the charging port capacitor through the conduction circuit, and control the charging port capacitor to discharge through the conduction circuit. Based on the above embodiments, not only can the voltage conversion device accommodate charging facilities of different voltage levels, but the charging port capacitor can also be pre-charged and discharged through the aforementioned conduction circuits, achieving safe and effective charging even when the voltage levels of the power battery and the charging facility are mismatched.
