Mung Bean Soup for Summer Heat

Mung Bean (Vigna radiata) soup is the quintessential summer beverage across East Asia. When the weather is sweltering and humid, traditional frameworks recommend this simple, slightly sweet broth to 'clear Summer Heat' and 'resolve toxicity.' The mung bean is highly valued for its cold nature, which rapidly cools the body, quenches thirst, and soothes the irritability that often accompanies extreme heat. Modern nutritional science supports the use of mung beans for heat relief — they are exceptionally rich in potassium, magnesium, and B vitamins, electrolytes that are rapidly lost through sweating.

Readers who search mung bean soup usually want the classic summer cooling version, so this page keeps the ingredient list short and the method straightforward.

Why It Works: Tradition Meets Science

Mung Bean (Vigna radiata) soup is the quintessential summer beverage across East Asia. When the weather is sweltering and humid, traditional frameworks recommend this simple, slightly sweet broth to 'clear Summer Heat' and 'resolve toxicity.' The mung bean is highly valued for its cold nature, which rapidly cools the body, quenches thirst, and soothes the irritability that often accompanies extreme heat.

Modern nutritional science supports the use of mung beans for heat relief. Mung beans are exceptionally rich in potassium, magnesium, and B vitamins—electrolytes and nutrients that are rapidly lost through sweating. Furthermore, the seed coat of the mung bean contains potent flavonoid antioxidants (like vitexin and isovitexin) that have been shown to protect cells against heat-induced oxidative stress. The soup acts as a natural, hydrating electrolyte replacement that supports cellular resilience during hot weather.

Safety and Caution Details

Mung bean soup is an excellent, hydrating food for hot weather. However, because the beans are energetically 'cold,' traditional practice advises against consuming large quantities of chilled mung bean soup if you have a 'cold' digestive constitution (characterized by a tendency toward loose stools, a pale tongue, or feeling cold easily).

Pregnant women and those taking prescription medications should consume it in moderation, as its strong 'clearing' nature may interact with certain wellness protocols.

Recipe basics

Ingredients

Yield: 2 to 3 servings | Prep: 5 min | Total: 25 min (clear broth) to PT55M (hearty soup)

  • 1/2 cup dried mung beans (Vigna radiata), rinsed well
  • 5 to 6 cups water
  • 2-3 tablespoons rock sugar or raw cane sugar (adjust to taste)
  • Optional: A small piece of dried tangerine peel (Chen Pi) to aid digestion

Step by step

How to make it

  1. Rinse and soak (optional): Rinse the mung beans thoroughly. While not strictly necessary, soaking them for 1-2 hours can speed up the cooking time.
  2. Boil the water: In a medium pot, bring the 5-6 cups of water to a rolling boil.
  3. Add the beans: Add the rinsed mung beans (and the tangerine peel, if using) to the boiling water.
  4. Simmer for clear broth (for heat relief): If your primary goal is rapid cooling and hydration, boil the beans for just 15-20 minutes until the water turns a clear, greenish-yellow, but the beans have not yet burst. You can drink this clear broth throughout the day.
  5. Simmer for a hearty soup: If you prefer a more substantial dessert soup, reduce the heat, cover, and simmer for 40-50 minutes until the beans burst open and the soup becomes slightly cloudy and thick.
  6. Sweeten: Stir in the rock sugar until dissolved. Remove from heat.
  7. Serve: Mung bean soup can be served warm, at room temperature, or chilled in the refrigerator for a refreshing summer treat.

Serving notes

Keep it simple

  • The clear broth version (15-20 minute simmer) is ideal for rapid cooling and hydration — the water turns a clear, greenish-yellow color.
  • The hearty soup version (40-50 minute simmer) is better as a more substantial dessert soup, with the beans bursting open and the soup becoming slightly cloudy.
  • Chen Pi (aged tangerine peel) is a traditional addition that helps support digestion and balance the cooling nature of the beans.
