E Guan Cao (Kamoji Wildrye) is the name of a traditional Chinese medicine. It is the whole plant of Roegneria kamoji Ohwi, a plant in the family Poaceae. It mainly grows on hillsides and in moist grasslands.

Efficacy & Actions

Clears Heat and cools Blood; relieves pain.

Indications

Cough with blood-streaked phlegm; wind rash (wind-type urticaria; fengdan); pain due to overexertion and strain.

Modern Pharmacology

Modern pharmacological research on Kamoji Wildrye remains insufficient. Available data only record its resistance to Fusarium head blight (scab), which is an agronomic characteristic rather than a pharmacological activity study in humans. Dedicated systematic pharmacological research on Kamoji Wildrye is extremely limited, and the modern scientific basis for its traditional effects remains to be further explored. When used, traditional actions and indications should remain the primary basis.

Ingredients

Systematic chemical studies on Kamoji Wildrye remain insufficient. Existing literature mainly concerns constituents related to its agronomic traits, such as the high-molecular-weight glutenin subunit (HMW-GS 1St1.2), which is composed of 404 amino acids. The air-dried matter at the booting stage contains 12.93% crude protein, 4.14% crude fat, 26.16% crude fiber, 38.12% nitrogen-free extract, 9.6% crude ash, 0.45% calcium, and 0.28% phosphorus. The above data are derived from forage nutritional analysis and do not constitute systematic research on medicinal chemical constituents.

Usage & Dosage

Oral use: Decocted in water or steeped in alcohol, 10–30 g.

Contraindications

Pregnant women should use it with caution. Individuals with Spleen-Stomach deficiency cold should use it with caution.

Daily Consumption

Kamoji Wildrye was historically used as a famine-relief plant. According to ancient records, “It is gathered in the second month and eaten cooked; it can also be made into pickles.” That is, the tender shoots were gathered during the first and second lunar months, cooked, and eaten, or chopped and made into pickled vegetables. Its leaves are soft and can also be used as livestock feed. In modern times, it is generally not used as a daily food.

Medicinal Parts

Whole plant.
