Yi Zhi Ren and Yuan Zhi Herbal Tea

Why people make this tea

Nourilo recalls that when he was studying Chinese herbal medicine, the sheer number of names and synonyms for each herb made memory itself a challenge — and it was partly through drinking preparations like this one that he kept his mind sharp through those years of study. Today he recommends this simple two-herb tea most often to older adults noticing the early signs of age-related cognitive change, and to students who want to support concentration during exam periods.

Yi zhi ren (alpinia fruit) and yuan zhi (polygala root) are a classic pairing in Chinese medicine. Together they are traditionally understood to support the communication between the heart and kidney systems — which in Chinese medical thinking governs memory, sleep quality, and mental stability. The tea has a distinct, aromatic quality that some find pleasant and others find strong; adding longan flesh softens the flavour considerably.

Method

1. Lightly crush the yi zhi ren before using — this helps release its flavour and active compounds more effectively.
2. Place both herbs (and optional longan or dates) into a small pot with 2–3 cups of water.
3. Bring to a boil, reduce heat, and simmer for 15 minutes. Alternatively, place in a teapot, pour on boiling water, cover, and steep for 15 minutes.
4. Strain and drink warm. The tea can be re-steeped once with fresh water. One day’s supply is approximately 2 cups.
5. For sustained support, take 3–4 times per week rather than daily — give the body time to respond naturally.

Nourilo’s Tips

This tea has a noticeable herbal aroma — some people find it pleasant, others find it a little sharp or unfamiliar. Adding 8 longan pieces to the pot transforms the experience: longan has its own mild brain-nourishing quality and brings a natural sweetness that makes the tea very easy to drink. Nan zao (southern dates) is another good addition for sweetness and gentle tonifying effect.

For a four-person family dose, scale up to 15 g of each herb with 1,500 mL of water and simmer for 30 minutes. Adding the optional herbs (longan, nan zao) can be done freely according to taste.

Also consider incorporating brain-nourishing foods into your daily diet: walnuts, golden needle mushroom (jin zhen gu), black sesame, black beans, goji berries, dried oyster, longan, and egg-based dishes are all traditionally valued for supporting brain function and can complement this tea.
