Why people make this tea
In Chinese medicine, the liver is closely connected to the eyes. When liver qi becomes constrained or liver fire rises — often triggered by long hours of work, stress, insufficient sleep or too much screen time — symptoms such as red, sore and swollen eyes, throbbing headaches and irritability tend to follow. This tea was developed precisely for that pattern.
Prunella spike (xia ku cao) is considered one of the key herbs for clearing liver fire in Chinese medicine, and has long been used for red and swollen eyes, headache and dizziness from liver fire rising upward. Modern research suggests it may also have a blood-pressure-lowering effect and has been studied in oncology contexts. Chrysanthemum and cassia seeds reinforce this eye-clearing and pressure-supporting action. Nourilo recommends it as a household tea for anyone in the family who has high blood pressure, or who regularly feels irritable, headachy and eye-strained from demanding work.
What studies say about the key ingredients
Traditional use is not the same as clinical proof. Here is the strongest human research we found for each ingredient, limitations included.
- Chrysanthemum
Compared with the high-fat meal alone, the extract group had lower postprandial glucose at 1 hour and higher antioxidant markers (T-AOC, SOD, GSH), with lower MDA. Incremental area under the curve did not differ significantly between groups.Limitation: Small sample of healthy young adults given a single high-fat meal, so longer-term effects and effects in people with metabolic conditions are unknown.PubMed 36677639 · 1 more chrysanthemum study
