1️⃣ Why Winter Radish Is Called “Dong-sam (Winter Ginseng)”
Every winter, many people experience recurring issues such as knee pain, poor digestion, dry cough, and mucus build-up. These symptoms often result from cold temperatures weakening immunity, circulation, and metabolic activity.
In traditional Korean texts, winter radish was regarded as “Dong-sam,” a healing food considered as valuable as wild ginseng. This is because radish offers a unique combination of digestive support, bone nourishment, immune boosting, respiratory benefits, and anti-inflammatory activity.
“The harsher the winter cold, the more healing a warm radish dish becomes.”
2️⃣ Three Hidden Factors That Disrupt Health in Winter
Winter discomfort is not just fatigue; it reflects three major functional declines in the body:
- ① Bone & joint weakening — lower vitamin D, reduced outdoor activity
- ② Slowed digestion — decreased enzyme activity, reduced gut diversity
- ③ Respiratory vulnerability — dry mucous membranes, higher viral exposure
This article presents three expert-level radish recipes designed to address all three issues at once.
3️⃣ Radish Nutrition & Benefits — Scientifically Explained
Although radish is high in water content, it is nutritionally rich, offering vitamin C, calcium, fiber, digestive enzymes, and anti-inflammatory compounds.
① Calcium & Vitamin D — Essential for Winter Bone Strength
Fresh radish contains ~20 mg of calcium per 100 g, but when dried, its calcium density increases by up to 15 times (≈310 mg).
Research from Asan Medical Center shows that vitamin D can raise calcium absorption by up to 30%, making it essential for bone maintenance.
② Enzymes (Diastase, Lipase, Protease) — Natural Digestive Support
Radish contains enzymes that help break down carbohydrates, fats, and proteins.
③ Sinigrin & Isothiocyanates — Respiratory & Anti-Inflammatory Effects
These compounds help ease cough, reduce mucus, and support detoxification. Studies from the Korea Food Research Institute indicate that heat enhances their activity.

4️⃣ Three Science-Based Radish Recipes
1) Dried Radish–Ginger Tea — For Bone & Knee Support
Why It Works
Drying radish increases calcium up to 15-fold and encourages natural vitamin D formation. Ginger’s gingerol and shogaol compounds help reduce joint inflammation.
According to the Korea Food Research Institute, the anti-inflammatory compounds in radish and ginger become more active when heated.
How to Make It
- Prepare 20 g dried radish + 10 g fresh ginger.
- Simmer in 1 L of water for 20 minutes after boiling.
- Drink warm to enhance calcium absorption and reduce inflammation.
2) Radish–Carrot Pickles — For Digestion & Gut Health
Why It Works
Radish contains diastase, an enzyme that supports digestion. Carrots contain fructooligosaccharides that nourish beneficial bacteria such as *Bifidobacterium* and *Lactobacillus*.
Studies from the Korean Society of Food Science show that carrot peel contains a higher concentration of prebiotic compounds.
How to Make It
- Julienne 150 g radish (with skin) and 100 g carrot (peeled).
- Mix vinegar 5T + sugar 4T + salt 1t to make the brine.
- Refrigerate for 30 minutes before serving.
3) Radish–Pear Honey Tonic — For Cough & Respiratory Support
Why It Works
Radish’s sinigrin promotes mucus secretion to ease dry coughs. Pear peel contains flavonoids with strong antioxidant and anti-inflammatory effects.
According to research from the Rural Development Administration, pear peel contains up to 4× more antioxidants than the flesh.
How to Make It
- Prepare 400 g radish + 200 g pear + a small amount of honey.
- Blend (with peel) and store in a glass jar.
- Let sit for one day; mix with warm water when drinking.
