A Look at the Benefits and Effects of Plantain: Clearing Heat, Promoting Urination, and Points to Note When Eating It

Plantain (Plantago asiatica) is a perennial herb in the genus Plantago of the family Plantaginaceae, also known as cartwheel grass, ox-tongue grass, and pig's-ear grass. It mostly grows in moist places such as field edges, roadsides, and ditch banks. Both its whole plant and its seeds can be used as medicine, and the seeds are the Chinese herbal medicine known as Plantaginis Semen (cheqianzi). As a wild plant used both as medicine and food, its tender spring leaves can be blanched and served cold, cooked in soup, or used as a filling, making for quite a variety of ways to eat it.

In traditional Chinese medicine, plantain is considered cold in nature and sweet in flavor, and it has traditionally been valued for clearing heat and promoting urination, draining dampness and relieving strangury, improving eyesight, and resolving phlegm. It is often used in combination formulas for difficult urination, edema, summer-damp diarrhea, and red, swollen, painful eyes. Among these, its diuretic and strangury-relieving effects are the best known, and in folk practice it is often boiled in water and drunk as a tea when urine is scanty and dark or urination is difficult. However, how exactly to use it should still be based on a pattern diagnosis under the guidance of a doctor or pharmacist.

When eating it, it is recommended to pick the tender leaves of spring, and the gathering site should avoid easily polluted areas such as roadsides and the vicinity of factories, nor should areas sprayed with pesticides be chosen. The fresh leaves should first be blanched in boiling water, which both removes the bitter taste and moderates its cold nature. After being dried in the sun, it can also be steeped in water, cooked in congee, or stewed in soup with lean meat and other ingredients, all of which are common home uses.

It should be noted that plantain is rather cold in nature, so people with weak and cold spleens and stomachs who are prone to diarrhea should not eat much of it, and pregnant women and those taking medication should consult a doctor before use. It can only serve as an aid to daily diet and conditioning and cannot replace proper treatment. If discomfort persists, medical attention should still be sought promptly so as not to delay the condition.
