Mirabilis Root (Di Lao Shu), Fresh Smilax, Turtle Plastron and Pork Bone Soup

Why people make this soup

The mirabilis plant (紫茉莉, four-o’clock flower) is a familiar sight in traditional gardens, and its fat, dark root — which does look a bit like a small black mouse, hence the name — has a mildly sweet, neutral flavour and has been used in traditional Cantonese cooking to help clear accumulated heat and dampness from the body. Paired with fresh smilax rhizome — another well-known herb for damp-heat conditions — this soup has a long history as a household remedy for skin irritation, joint soreness, and that heavy, foggy feeling that can set in during hot, humid weather. Adzuki beans and coix seed support the diuretic, damp-clearing action, while turtle plastron adds a cooling, nourishing quality according to TCM theory.

Method

1. Blanch the pork bones and turtle plastron separately in boiling water for 2 minutes to remove impurities. Rinse and set aside.
2. Slice the mirabilis root and smilax rhizome and rinse thoroughly under cold water.
3. Soak the adzuki beans and coix seed in cold water for 20–30 minutes; drain and rinse.
4. Combine all ingredients in a large pot with 3 L of water.
5. Bring to a boil over high heat, then reduce to a gentle simmer.
6. Cook for 2 hours until the soup reduces to about 1.2–1.5 L.
7. Serve and drink warm.

Nourilo’s Tips

When sourcing the mirabilis root, choose medium or smaller pieces — oversized roots can have a coarser, less pleasant texture. Most Chinese herbal suppliers will slice it for you on request, or you can slice it yourself at home. Mirabilis root is available at Chinese or Asian grocers, or online. If handling turtle plastron feels daunting, you can leave it out; the soup is still effective. This soup can also be made vegetarian by omitting the pork bones — it is naturally sweet and flavourful without meat. If you have already been diagnosed with a skin condition, this soup can be a helpful dietary addition while also seeing a doctor for treatment.
