Where is Lysimachia christinae distributed? A list of the latest main production areas
Lysimachia christinae is a perennial creeping small herb of the Primulaceae family, also known as Dijinqian, Qianqianjin, Lianqiancao, Guoluhuang, Jingmiancao, etc. It is a common plant and also a traditional Chinese medicinal herb. Its main effects can prevent kidney stones and promote bile secretion and stone expulsion. It can be said to have a very good therapeutic and preventive effect on stones. Now let us take a look at the production area distribution of Lysimachia christinae!
Production area distribution of Lysimachia christinae
Lysimachia christinae is distributed in all provinces south of the Yangtze River in China and in Taiwan, China. It is widely spread across tropical and subtropical regions of both hemispheres, growing wild and cultivated on mountain slopes, grasslands, roadsides or ditch edges at altitudes of 1300-1980 m.
Growing environment of Lysimachia christinae
Lysimachia christinae has strong adaptability to the pH of water bodies, but it is best to keep it between 6.5-7.5. It likes warmth, avoids high temperatures, and tolerates low temperatures. It grows well within a temperature range of 16-24°C, and the overwintering temperature should not be lower than 5°C. When the room temperature exceeds 30°C, plant growth will be inhibited. It likes moisture and is more commonly seen in places with flowing water sources.
Efficacy and effects of Lysimachia christinae
1. Stone expulsion effect: Lysimachia christinae has cholagogic and litholytic effects and diuretic and litholytic effects. The polysaccharide components in the insoluble matter inhibit the crystallization of calcium oxalate monohydrate CaC2O4·H2O, the main component of urinary tract stones, and the inhibitory effect increases with concentration. It can also make blood and urine acidic, dissolve stones that can only exist in an alkaline environment, slow the growth rate of CaC2O4·H2O, and reduce the degree of crystal aggregation, thereby helping to treat stones. It has been widely used in modern clinical practice and has achieved good results. People usually drink it steeped in water as a tea beverage because of its effect of clearing heat, promoting diuresis and expelling stones.
2. Cholagogic effect: Pharmacology and clinical practice have confirmed that it indeed has a cholagogic effect. The cholagogic effect may lie in promoting the secretion of bile by liver cells, increasing bile in the liver and gallbladder, raising internal pressure, relaxing the sphincter of Oddi, and thereby increasing bile excretion.
3. Thrombosis inhibition: Total flavonoids of Lysimachia christinae can significantly reduce the wet weight and dry weight of venous thrombosis in rats under pathological conditions, lower the percentage of thrombosis, and show a significant thrombosis-inhibiting effect.
4. Immune enhancement: Lysimachia christinae has an inhibitory effect on cellular immunity and can enhance the phagocytic function of mouse macrophages. Lysimachia christinae is beneficial as an immunosuppressant for organ transplantation or autoimmune diseases.
