Foods for clear skin · the Korean medicine view

Foods to keep close

Warm root vegetables, in season, gently cooked: radish, lotus root, sweet potato, doraji (platycodon).

Gentle proteins: white fish, tofu, slow-cooked chicken broth.

Pears, in autumn, raw or steamed — a traditional Korean lung-and-skin food.

Warm water, sipped through the day.

Foods to keep at a distance during a clearing cycle

Dairy, in any form. The Korean medicine view is that dairy thickens the inner mucosa.

Refined sugar and chilled sweets.

Alcohol, especially in the three hours before sleep.

Deep-fried, heavily spiced, and chilled raw foods.

How long is the cycle

Three months, the same as the constitutional formula. Most people notice changes in skin reactivity by week six.

Three starter recipes from the Korean home table

White-radish and Job’s-tears soup: half a daikon, 50 g of Job’s tears, a thumb of fresh ginger, 1.5 L of water, simmered 40 minutes with a pinch of salt. Two or three evenings a week as a side soup, especially during a clearing window.

Lotus-root and pork-rib soup: one section of lotus root sliced, 200 g of ribs, six red dates, simmered 1 hour in 1.5 L of water. Lotus root is moistening to lung and skin; the broth is gentle and not heating.

Korean-style platycodon banchan: 30 g of dried doraji rehydrated and shredded, dressed with sesame oil, sea salt, and a touch of apple-cider vinegar; sprinkled with white sesame. A daily side dish that quietly carries the lung-skin support into the meal.

Why dairy gets named

Korean medicine is direct about dairy because of long observation: in the “phlegm-damp” constitution Korean medicine describes, dairy tends to thicken mucosal secretions — which on the skin shows up as clogged pores, oily flaking, and recurring redness.

This isn’t a claim that dairy is bad. It’s that during a clearing cycle for recurrent skin issues, taking it off the equation lets you observe the skin’s response. After about six weeks, reintroduce it in small amounts and watch how your body responds. Each person is different — that’s the spirit of the constitutional method.

"The lung governs the skin" — dietary implications from the classics

The *Huangdi Neijing* ("Plain Questions, Generation of the Five Viscera") states plainly: "The lung pairs with the skin, its flowering is in the hair." The *Donguibogam* in "External Form" extends this: "The skin is the lung's external counterpart, its flowering in the hair." These root ideas place skin and lung as two faces of one system — foods beneficial to the lung also help the skin; foods burdening the lung with phlegm-damp also show up on the skin.

**Good for the lung, good for the skin:** Chinese yam, white fungus, lotus seed, lily bulb, platycodon, pear, mature ginkgo (cooked), coix seed, brown rice, dark leafy greens, fermented foods.

**Phlegm-damp on the lung, mirrored on the skin:** excess dairy, fried food, sugar, alcohol, spicy food, processed meat, shellfish.

This dietary lead isn't dogma; it follows the internal logic of "two organs, one system."

Advanced herbal ingredients — mulberry leaf, cassia seed, adenophora

For long-term care of recurrent skin issues, Korean medicine food therapy adds a few "advanced" herbs to the basic ingredients:

**Mulberry leaf:** clears the lung, moistens dryness, calms the liver, brightens vision. Dried mulberry leaves steeped in boiling water make a daily tea; or added to mung-bean soup. Best in dry autumn.

**Cassia seed:** clears the liver, brightens the eyes, lubricates the bowels. Cassia-seed tea is a common after-meal drink at Korean dinner tables. For those with recurrent skin issues, paired with sufficient water intake, it helps clear thermal metabolites.

**Adenophora:** nourishes yin, moistens the lung, benefits the stomach, generates fluids. Adenophora-chicken soup is a traditional yin-nourishing preparation, suitable for long-term skin sensitivity with dry mouth and dry tongue.

**Important reminder:** these botanicals are gentle in nature in traditional food therapy, but consult a licensed Korean medicine practitioner before long-term, large-dose use — especially when used alongside other prescription medications.
