Watercress Plant Introduction, Distribution, and Growth Environment

Watercress (scientific name: Silybum marianum) is a perennial herbaceous plant belonging to the Asteraceae family. Below is an introduction to the origin, distribution, and growth environment of watercress.

Origin of the Plant:

Watercress is native to the Mediterranean region, including southern Europe, North Africa, and southwestern Asia. It thrives in warm, dry climates and prefers fertile, well-drained sandy or stony soils. Watercress plants can grow up to 1.5 meters tall with bushy leaves and purple-red flowers. The fruits are hard-shelled pods containing oval seeds.

Distribution:

Watercress is primarily found in Mediterranean coastal regions, such as Spain, Italy, Greece, and Turkey, as well as in North African countries like Morocco, Tunisia, and Algeria. In these areas, watercress typically grows at lower altitudes and can be found along riverbanks, hillsides, and grassy areas.

Growth Environment:

Watercress prefers warm, dry climates and thrives in full sun or partial shade. It is not particularly demanding regarding soil quality, able to grow in calcareous, sandy, or gravelly soils, though it requires good drainage and dislikes waterlogging. Watercress needs plenty of sunlight during its growth period but can tolerate some shade. Its deep root system provides strong drought resistance, allowing it to thrive in arid regions as well.

In summary, watercress is a resilient plant with modest growth environment requirements, flourishing in the warm, dry regions of the Mediterranean coast, providing rich medicinal and nutritional resources.

Watercress Extract Processing and Storage

The processing of watercress extract typically includes the following steps: First, the seeds or parts of the watercress plant (such as fruits and leaves) are dried to reduce moisture content. Next, the dried plant materials are crushed or ground to enhance extraction efficiency. Then, appropriate extraction methods (such as infusion or ultrasound extraction) are employed to extract the active components of watercress. Finally, the extracted substances undergo filtration, concentration, and drying processes to yield watercress extract.

Regarding storage, watercress extract should be kept in a cool, dry, well-ventilated environment, away from direct sunlight and high temperatures. The optimal storage temperature is between 15 to 25 degrees Celsius, with relative humidity maintained between 50% to 60%. Additionally, it should avoid contact with harmful substances, and containers should be kept sealed to prevent moisture and impurities from entering. Proper storage methods help maintain the stability and efficacy of watercress extract, extending its shelf life.
