History and Traditional Uses of Hatomugi
Hatomugi is an annual grass, indigenous to South Asia, that was introduced to Japan 1200 years ago. Interestingly, it arrived in Japan with a wave of pomp and ceremony. A Chinese monk named Ganzin presented it together with Buddhist scriptures to the then Japanese emperor. It did not come into Japan quietly, rather with a band roll!

Its use was always two-fold – food and medicine. In Japanese, Hato means “dependable good harvest” and Mugi means wheat. As the name implies, Hatomugi is a stout and vigorous grower, thriving in a variety of locations including those not usually able to produce other crops. It thrives even in wastelands. The plant produces spike-like flowers in summer and bears brown oval fruits in autumn. Throughout Asia, the Hatimugi is seen as a reliable source of sustenance-the one crop that seems to produce no matter what.

When it first arrived in Japan it was used almost entirely by Chinese monks and Chinese medicine practitioners. As time passed, Japanese folk healers came to know it and it became an indispensable part of the Japanese medical repertoire. They saw it as a source of life-building food.

In Japanese folk medicine Hatomugi is seen as a tonic medicine which increases health and vitality amongst the well and improves the health of those that are ailing. In traditional Japanese medicine it is used to treat warts, rheumatism, gonorrhea, hypertension, appendicitis, arthritis, beriberi, bronchitis, cancer, diarrhea, dry skin, dysuria, edema, hydrothorax, inflammation, pleurisy , pneumonia, pulmonary abscess, tuberculosis. It is highly recommended to make the skin appear young and supple and to increase breast milk. These two uses are telling- both indicate the medicine is a boost to vitality.
