The overall structure allows the shrub to adapt to various environments through its resilient woody framework.
What is the geographical distribution of this plant?
This plant is native to various regions across China, specifically spreading throughout central and southern provinces like Henan, Hebei, and Shandong. It thrives primarily in temperate and subtropical climates where it can find suitable soil conditions. While its primary range is concentrated in East Asia, some varieties have been introduced to other parts of the world for cultivation. The species is frequently found in disturbed areas, hillsides, and along riverbanks within its natural habitats. Its ability to adapt to different environments allows it to occupy diverse ecological niches across its native landscape.
How is this plant cultivated?
This plant, Lycium chinense, is cultivated by planting seeds or cuttings in well-draining, sandy loam soils within full sunlight and temperate climates.
Growers must ensure the soil maintains a slightly alkaline to neutral pH to promote vigorous growth and fruit production. Regular irrigation is necessary during the initial establishment phase, though the mature shrubs are notably drought-tolerant once their root systems are deep. Pruning the branches during the dormant season helps maintain plant health and encourages more efficient harvesting of the red berries.
Careful management of soil nutrients and pest control is essential to maximize the yield of these medicinal berries.
What parts of this plant are used medicinally?
This plant Lycium chinense is used medicinally through its fructus, leaves, roots, flowers, and stems. The dried red berries, known as goji berries, are the most widely consumed part for their antioxidant properties. The leaves and flowers are often utilized in herbal infusions to support various bodily functions. Medicinally, the roots are processed to create decoctions that aim to nourish the blood and liver. Additionally, the stem can be incorporated into specific traditional formulations to balance the plant's overall therapeutic effects.
According to a study published by "Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica", the contents of zinc were measured in Fructus Lycii. This measurement was conducted under optimol experimental conditions. The research utilized the principle that the relative luminous strength of luminol-H2O2-Co2+ chemiluminescence quenching is extinguished by zinc. The study focused on the determination of micro amounts of zinc in medicinal herbs using the chemiluminescence quenching method.

What traditional systems uses this plant?
This plant, known as Lycium chinense, has been utilized for centuries within the framework of Oriental Medicine to treat various ailments related to kidney and liver functions. Practitioners traditionally prescribed the dried berries to nourish the blood and enhance visual clarity. In many historical contexts, it was integrated into complex herbal formulas to bolster the body's vital energy or qi. The fruit was often prepared as a tea or a medicinal tonic to promote longevity and overall vitality. These ancient applications laid the foundational understanding of the plant's restorative properties in Eastern therapeutic practices.
According to a study published by "Phytotherapy research : PTR", Lycium chinense provides components such as betaine, coumarin, and flavonoids. These components have been used in oriental medicine for the treatment of respiratory diseases. In the study, primary hamster tracheal surface epithelial cells were metabolically radiolabeled using (3)H-glucosamine for 24 h. The cells were then treated for 30 min in the presence of varying concentrations of each agent to assess the effects on (3)H-mucin release. This research investigated whether these natural products affect mucin release by comparing them to the inhibitory action of poly-L-lysine and the stimulatory action of adenosine triphosphaate.
