Eupatorium Fortunei (Pei Lan Herb)
What is Eupatorium Fortunei (Pei Lan Herb)?
Fortune Eupatorium Herb (pei lan, 佩兰), also known as Eupatorium Fortunei, is a bush-like plant that bears large clusters of flowers. Since ancient times, Eupatorium Fortunei has appeared in Chinese and Japanese literature for centuries. In ancient China, Eupatorium Fortunei was referred to as Lan Cao (兰草). In Japan, this plant was known as fujibakama, a term that was also applied to cultivated Eupatorium Flowers which have noticeable differences from the wild Eupatorium Fortunei.
A herbaceous perennial that grows up to 100 cm in height, Eupatorium Fortunei grows upright with green stems that are often tinted with reddish or purple dots.
This plant grows in many parts of the world, such as South America, Mexico, China, Japan and Korea. Eupatorium Fortunei is also frequently grown in home gardens as a decorative plant.
While Eupatorium Fortunei can grow in both shaded and sunny areas, it requires moist soil to thrive. The aerial parts of this plant, such as its flowers, leaves and stems, are often used in herbal remedies. The Pei Lan Herb is usually harvested in Summer and Fall, then cut into slices and dried under the Sun before medicinal usage.
In Traditional Chinese Medicine (TCM), the Pei Lan Herb falls under the category of ‘Aromatic herbs that transform Dampness’. Such herbs can resolve Cold-Damp Stagnation, especially in the stomach and the Spleen. Neutral in nature, this herb does not affect the yin-yang balance in the body.
Pungent in taste, Eupatorium Fortunei can promote the circulations of qi and body fluids. In particular, the Pei Lan herb targets the Spleen, the Lungs and the stomach.
Functions and Benefits of Eupatorium Fortunei (Pei Lan Herb)
Traditional Chinese Medicine (TCM) shows that Eupatorium Fortunei has the following health benefits.
Eupatorium Fortunei can resolve Dampness to relieve syndromes caused by Damp obstruction in the middle energizer. For example, the Pei Lan Herb can relieve poor appetite, nausea and stifling sensations in the chest.
As the herb can aromatically dispel Middle Jiao turbid filth to address the internal accumulation of increasingly thickened dampness in the Middle Jiao, the Pei Lan Herb can cure Damp-Heat in the Spleen that is manifested as symptoms such as sweetness and greasiness in the mouth, plenty of saliva, bad breath, halitosis, lethargy, fatigue, anorexia, epigastric and abdominal distention and pain as well. It is also suggested that Eupatorium Fortunei can help to correct imbalances associated with celiac disease, an autoimmune condition in which gluten consumption triggers damage to the small intestines.
Eupatorium Fortunei can also dispel Summer-Heat to release the exterior and resolve Damp-turbidity from the interior. This makes the Pei Lan Herb a great herb to relieve symptoms such as fever, headache, chest fullness and greasy tongue coating.
