Walnut Partition (Fen Xin Mu), Lotus Seed, Fox Nut & Ginkgo Soup

Why people make this soup

Fen xin mu — the woody inner partition of the walnut — is a little-known ingredient that looks like irregular fragments of walnut shell. Available at traditional herb shops, it has an extensive list of traditional uses: consolidating kidney essence, reducing urinary leakage, addressing excessive vaginal discharge, and calming the nervous system. It can also be brewed as a simple tea for insomnia and nervous weakness. Paired with the better-known consolidating trio of lotus seeds, fox nuts, and ginkgo nuts, fen xin mu rounds out a soup that addresses multiple related symptoms simultaneously. It can be cooked as a sweet dessert soup with rock sugar or as a savoury soup with lean pork — both work well.

Traditional use is not the same as clinical proof. Here is the strongest human research we found for each ingredient, limitations included.

  • Walnuts · Randomized controlled trial, 305 participants · 2019
    Office systolic BP changed by -4.61 mm Hg with walnuts versus -0.59 mm Hg in controls (P=0.051); 24-hour ambulatory systolic BP difference was not significant (P=0.111). No diastolic BP changes were observed.Limitation: Only 236 of 305 participants (75%) completed the study, and the main between-group differences did not reach conventional significance.PubMed 30879358 · 2 more walnuts studies
  • Lotus seeds · Randomized crossover trial, 10 participants · 2019
    Lotus seed meals had a low glycemic index (GI 21–51 across the lotus seed and adzuki bean meals), while several other starchy foods did not differ significantly from rice. Lotus seed's in vitro hydrolysis index was also lower than that of other test foods.Limitation: Only ten healthy participants and acute single-meal tests, so findings may not apply to people with diabetes or to long-term intake.PubMed 30875961
