Why people make this tea

After a cold or a bout of COVID, a lot of people are left dragging — a cough that won’t quit, breathlessness, tiredness, a foggy head, night sweats, even trouble sleeping. Nourilo likes this gentle three-herb tea for exactly that in-between recovery stage. Astragalus is the classic “energy and immune” herb, ophiopogon brings moisture back to a dry chest, and schisandra helps settle the cough and calm a restless night. It’s an easy daily sip while you get your strength back.

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.

  • Astragalus root · Meta-analysis, 8 studies, 750 participants · 2025
    TA-65 was associated with longer leukocyte telomeres compared with controls, but the meta-analysis found no significant improvement in frailty measures or inflammatory markers (CRP/IL-6). Mild gastrointestinal effects were reported.Limitation: Industry-funded trials reported larger effects than others, and the compound is a purified extract at doses not comparable to eating Astragalus root.PubMed 41286474 · 3 more astragalus root studies
  • Schisandra berries · Randomized controlled trial · 2021
    Compared with placebo, the extract group had a higher increase in right knee extensor strength (10.2 Nm) and left knee extensor strength (6.7 Nm). No group differences were found in muscle mass, inflammatory or antioxidative markers.Limitation: Small sample over 12 weeks, with an extract dose not comparable to eating the whole berry; muscle mass and blood markers did not differ.PubMed 33710261 · 2 more schisandra berries studies
