Poria Product Introduction

Poria is a commonly used Chinese medicinal herb, rich in polysaccharides, triterpene saponins, and poria phenol. It is derived from the sclerotium of the perennial fungus *Poria cocos*. Poria has a long history of use in traditional Chinese medicine. According to TCM principles, Poria is neutral in nature and sweet in flavor, and it affects the spleen, stomach, and lung meridians. It helps promote urination, drain dampness, strengthen the spleen, calm the mind, and improve mental function. Therefore, it is frequently used to treat conditions like excessive dampness, water retention, and spleen-stomach weakness. Poria is a dual-purpose herb that is applied both medicinally and as a food ingredient, widely used in TCM and the food industry.

Poria Source Plant Introduction, Distribution, and Growth Environment

Poria, scientifically known as *Poria cocos*, is a significant traditional Chinese medicine herb from the Polyporaceae family. The fruiting body of this fungus is used as the medicinal material known as Poria. The following details its source plant, distribution, and growth environment.

  1. Plant Introduction:
    1. Poria belongs to the Polyporaceae family of fungi, which are closely related to plants but are classified as fungi. The fruiting body of Poria is typically disk-shaped or irregularly blocky, with a porous surface and a firm texture.
    2. Poria primarily grows in moist environments and typically attaches itself to the roots of certain plants, forming visible tuber-like structures underground.
  1. Distribution:
    1. Poria is widely distributed, primarily found in regions such as China, Japan, Korea, Vietnam, and Myanmar.
    2. In China, Poria is commonly found in areas such as South China, Central China, East China, and Southwest China. Key producing regions include Hunan, Hubei, Fujian, and Guangxi.
  1. Growth Environment:
    1. Poria thrives in moist, cool environments, typically growing on the roots of trees such as pine, cypress, fir, and beech. It can also be found in bamboo groves or on the edges of forests.
    2. The underground tuber-like structures of Poria are found near the root systems of plants, requiring appropriate humidity and ventilation for growth.

The growth environment of Poria is crucial for its quality and medicinal value, so ecological protection must be prioritized during cultivation and harvesting to avoid overexploitation and environmental damage.

Poria Harvesting, Processing, and Storage

The harvesting, processing, and storage of Poria are critical to maintaining its medicinal value and quality. Below are the steps involved in these processes:

  1. Harvesting:
    1. Poria is usually harvested in the autumn or winter when the fruiting bodies are fully mature.
    2. Care must be taken during harvesting to remove the entire Poria block without damaging the roots of the host plant, and to protect the ecological environment.
    3. After harvesting, the Poria should be cleaned to remove dirt and impurities, then dried or air-dried to an appropriate moisture level.
  1. Processing:
    1. Processing of Poria typically includes slicing and drying to better preserve and prepare it for use.
    2. Fresh Poria can be cleaned, sliced, and dried in the sun, or directly air-dried until the moisture content is suitable.
  1. Storage:
    1. Dried Poria should be stored in a cool, dry, and ventilated area, away from direct sunlight and moisture.
    2. It is best stored in breathable containers such as cloth bags or bamboo baskets, ensuring it does not come into contact with damp items.
    3. Long-term storage requires regular inspection to check for insect infestations or mold. If any issues are found, the affected material should be removed to prevent it from affecting the quality of the remaining Poria.

Poria is sensitive to moisture, mold, and pests during storage, so it is essential to choose suitable storage environments and methods, with periodic inspections to ensure its quality and medicinal value. Additionally, processing and storage must comply with hygiene standards to guarantee the safety and quality of Poria.
