Herbal Teas
Yizhiren (Alpinia Oxyphylla Fruit) Tea
Yizhiren Tea is a classic warming tonic medicinal tea rooted in Traditional Chinese Medicine. Yizhiren is the dried ripe fruit of the ginger family plant Alpinia oxyphylla, first recorded in the Tang Dynasty Bencao Shiyi, also known as Yizhi Zi or “Scholar’s Fruit.” The Compendium of Materia Medica records that it “benefits essence and qi and strengthens the will.” It is pungent in taste, warm in nature, entering the Spleen and Kidney meridians, with the effects of warming the kidneys, astringing essence, reducing urination, warming the spleen, stopping diarrhea, and controlling salivation. Brewed as a tea, the liquid is pale yellow with a distinctive herbal pungency and a warm, slightly pungent taste. It is especially suitable for those with kidney yang deficiency manifesting as frequent urination, enuresis, spleen-cold diarrhea, and excessive salivation.
Main Ingredients
- Yizhiren (Alpinia oxyphylla fruit) 5-10g
- Hot water 300-500ml
- Honey or rock sugar to taste
- Goji berries 5-10g
- Red dates 2-3 pieces
Steps
Take 5-10g of salt-fried Yizhiren and rinse quickly to remove surface dust. Lightly crush or slice to release active compounds.
Put the crushed Yizhiren into a teacup or thermos. If using 5-10g goji berries or 2-3 red dates, add them together.
Pour 80-90°C hot water (about 300-500ml) over the ingredients. The active compounds in Yizhiren dissolve well at high temperatures; boiling water helps release its medicinal properties.
Cover and steep for 10-15 minutes until the liquid turns pale yellow and active compounds are fully released. Add honey or rock sugar to taste if desired. Consume 1 dose daily, drinking frequently as tea. Can be re-brewed 2-3 times until the flavor fades.
