Overview of the health benefits of Ophiopogon japonicus

Ophiopogon japonicus, as a traditional Chinese medicinal material, has core functions such as moistening the lungs and nourishing yin, replenishing the stomach and promoting fluid production, clearing the heart and removing troubles, and is widely used in daily health care and traditional Chinese medicine conditioning. Its main functions can be divided into three categories:Nourishing yin and moisturizing dryness(Improve dry cough and dry mouth),Regulate immunity(increases resistance) andcardiovascular protection(Assistant in lowering blood sugar and anti-arrhythmia). Secondary effects include relieving constipation and improving sleep. Modern research also shows that it contains active ingredients such as saponins and polysaccharides, further verifying the scientific nature of its traditional effects.

Moisten the lungs and nourish yin: relieve autumn dryness and respiratory discomfort

The lung-moistening effect of Ophiopogon japonicus is listed as "top grade" in "Shen Nong's Materia Medica", and it is especially suitable for dry autumn or long-term smokers. Its mucus component can moisturize the respiratory mucosa and relieve symptoms such as dry cough and dry itchy throat. The famous traditional Chinese medicine prescription "Adenophora and Ophiopogon japonicus decoction" uses Ophiopogon japonicus as the main medicine and is used to treat lung yin deficiency. Modern research has found that Ophiopogon japonicus polysaccharides can promote tracheal secretion and protect lung tissue (quoted from a 2021 study in the "Chinese Journal of Traditional Chinese Medicine"). Daily, 5-10 grams of Ophiopogon japonicus can be soaked in water instead of tea, or stewed with pear and lily to enhance the effect.

Benefit the stomach and promote fluid production: regulate spleen and stomach deficiency heat

The stomach-nourishing effect of Ophiopogon japonicus is recorded in the "Compendium of Materia Medica" as "maintaining Qi in the heart and heart, and insufficient stomach yin". For dry mouth and loss of appetite caused by strong stomach fire, Ophiopogon japonicus can improve digestive function by promoting gastric juice secretion. Clinical studies have shown that Ophiopogon japonicus extract has a repairing effect on patients with chronic gastritis and mucosal damage (see the table below for data). When used with Dendrobium and Polygonatum odoratum, the effect is more significant. It should be noted that those with spleen and stomach deficiency should be combined with ginger or red dates to neutralize their coolness.

Clearing away troubles and protecting cardiovascular system

The "heart-clearing" effect of Ophiopogon japonicus is reflected in improving symptoms of heart yin deficiency such as palpitations and insomnia. Ye Tianshi, a physician in the Qing Dynasty, once used "Ophiopogon japonicus and lotus seed soup" to treat deficiency and insomnia. Pharmacological experiments have confirmed that Ophiopogon japonicus saponins can regulate calcium channels in cardiomyocytes and help stabilize heart rhythm ("Chinese Patent Medicine" 2019 study). In addition, its polysaccharide content may reduce the risk of atherosclerosis through antioxidant pathways. It is recommended that menopausal women or those who stay up late for a long time use Ophiopogon japonicus with jujube kernels and cypress kernels to cook porridge.

Scientific use and precautions

Although Ophiopogon japonicus is a product of the same origin as medicine and food, it needs to be used based on syndrome differentiation. It should not be used by those suffering from colds, colds and diarrhea; for daily health care, it is recommended that the daily dosage should not exceed 15 grams. Common products on the market includeKangmei PharmaceuticalOphiopogon japonicus slices,TongrentangOphiopogon japonicus and wolfberry granules, etc. Research data shows that continuous use of Ophiopogon japonicus preparations for 4 weeks can improve dry mouth symptoms by 76% (2022 survey by Beijing University of Chinese Medicine). It is recommended to use other medicinal materials according to your constitution under the guidance of a doctor to achieve a synergistic health-preserving effect.
