Lythrum Salicaria

What is Lythrum Salicaria?

Lythrum Salicaria (jin qian cao, 金钱草), also known as Christina Loosestrife or Herba Lydimachiae, refers to the whole plant of Lysimachia christinae, which belongs to the Primulaceae family. With a Chinese name that means ‘Gold Coin Grass’, this plant has coin-like leaves and medicinal properties that are believed to be as precious as gold.

Usually collected during summer and autumn, people will remove the impurities on the plant, dry it under the sun and cut it into sections for medicinal usage.

In Traditional Chinese Medicine (TCM), Lythrum Salicaria falls under the category of ‘Herbs that drain Dampness’. Such herbs are typically diuretics that can increase urine production to remove Dampness that has accumulated in the body. Cool in nature, Lythrum Salicaria can help individuals who have too much Heat in their body, such as those experiencing a yang excess or a yin deficiency, to restore a harmonious yin-yang balance.

Salty and sweet in taste, Lythrum Salicaria has a draining effect on the body by clearing accumulations, removing Phlegm and softening hard lumps. Also, Lythrum Salicaria can slow down acute reactions, detoxify the body and has a tonic effect on the body by replenishing qi and blood. In particular, Lythrum Salicaria targets the bladder, gallbladder, Kidneys and Liver.

Not only can Lythrum Salicaria drain and remove Dampness, the herb can also clear Heat from the Liver and gallbladder. Thus, it is indicated for jaundice caused by Damp-Heat accumulated in the liver and gallbladder, red and swollen eyes, as well as for dysfunction of the Liver and gallbladder. 

Great at draining Damp-Heat from the lower energizer, Lythrum Salicaria can induce diuresis to treat stranguria. This herb can clear and excrete Damp-Heat from the Liver and gallbladder to relieve urolithic stranguria, Heat stranguria and gallbladder stone.
