Fresh Burdock, Corn, Shiitake and Pork Rib Soup

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.

• Burdock root · Randomized controlled trial, 60 participants · 2026
  Compared with placebo, root powder was associated with higher superoxide dismutase and catalase, lower malondialdehyde and C-reactive protein, and smaller ovarian volumes. Hirsutism and menstrual frequency results are not reported in the abstract.Limitation: Small single-centre trial of 60 women, recruited by convenience sampling. The 460 mg/day dose is much smaller than typical food intake.PubMed 41757842 · 2 more burdock root studies
• Goji berries · Meta-analysis, 161 participants · 2012
  Compared with placebo (n=80), the goji juice group (n=81) reported greater improvements in several self-rated symptoms, including stress, mental acuity, sleep quality and overall well-being, under a random effects model.Limitation: Outcomes were self-reported symptom questionnaires, and several symptoms showed significant heterogeneity across the four pooled trials of a single branded juice.PubMed 22897500 · 3 more goji berries studies
• Shiitake mushrooms · Randomized controlled trial · 2015
  Daily shiitake intake was associated with increased ex vivo proliferation of γδ-T and NK-T cells, higher salivary sIgA and lower serum CRP, along with changes in cytokine patterns. The comparison was before versus after intake in two dose groups.Limitation: Parallel 5 g and 10 g dose groups with no placebo or non-mushroom control. Short 4-week study in healthy young adults, with mostly ex vivo immune markers.PubMed 25866155 · 2 more shiitake mushrooms studies
