Ssuk (Artemisia princeps) is a perennial herb that grows abundantly across Korea and has been a cornerstone of traditional Korean medicine and cuisine for over 2,000 years. It is closely related to Japanese yomogi and Chinese ai ye, all members of the Artemisia family, but Korean varieties are prized for their distinct aromatic profile and potent phytochemical content. The herb appears in Korean folk medicine, Buddhist temple food traditions, spring rice cakes (ssuk tteok), and formal herbal pharmacy — making it one of the most culturally embedded medicinal plants in East Asia.

Ssuk works through several overlapping pathways: its flavonoids, especially eupatilin and jaceosidin, calm inflammatory signals in the gut lining and throughout the body. Its essential oils (including eucalyptol and camphor) have antispasmodic effects that help relax smooth muscle in the digestive tract and uterus, easing cramping. Its polyphenols and chlorogenic acid contribute antioxidant activity that helps protect cells from oxidative stress.

Dried ssuk tea is the most traditional and widely accessible form — steeped for 5–10 minutes and drunk warm. Powdered ssuk is added to rice cakes, soups, and smoothies. Standardized extracts and capsules (often standardized to eupatilin content) are used in clinical and supplement settings for more precise dosing. Topical compresses, baths, and moxibustion use the herb's essential oils externally for circulation, muscle relaxation, and menstrual support.

• Digestive discomfort, gastritis, and bloating
• Menstrual pain and cramps
• Irregular or painful periods
• Chronic inflammation
• Stomach ulcers and gut lining damage
• Poor circulation and cold extremities
• Anxiety and mild nervous tension
• Skin irritation and eczema (topical)
• Low appetite and sluggish digestion
• Joint pain and arthritis

• Recurrence of gastric mucosal damage (eupatilin shown to support stomach lining resilience)
• Oxidative cell stress (high polyphenol and flavonoid content provides antioxidant defense)

• Ssuk tteok (Korean mugwort rice cake) — The most traditional way to consume ssuk — fresh or dried herb is blended directly into rice dough, delivering the full spectrum of flavonoids and aromatic compounds in a culturally beloved form.
• Ssuk cha (mugwort tea) — Dried ssuk steeped in hot water extracts the water-soluble polyphenols, chlorogenic acid, and some flavonoids — the classic medicinal preparation used in Korean homes for digestion and menstrual support.
• Ssuk doenjang guk (mugwort soybean paste soup) — Fresh ssuk leaves are added to Korean fermented soybean soup in spring, combining the herb's active compounds with gut-friendly fermented ingredients for a traditional digestive tonic meal.
• Ssuk namul (blanched mugwort side dish) — Lightly blanched and seasoned young ssuk shoots are eaten as a banchan (side dish) — a simple way to consume the herb's phytochemicals as part of a regular Korean meal.
• Ssuk juk (mugwort porridge) — A gentle, warming porridge made with rice and fresh ssuk — traditionally given to those recovering from illness, with digestive and anti-inflammatory benefits in an easily absorbed form.

• Stomach upset or nausea at high doses
• Allergic reaction (skin rash, itching, sneezing) — especially in ragweed-sensitive individuals
• Contact dermatitis with prolonged topical use in sensitive skin
• Possible uterine stimulation — avoid medicinal doses during pregnancy
• Mild drowsiness when combined with sedating herbs or medications
• Rare: headache or dizziness with essential oil inhalation in enclosed spaces

• Recommended daily: Dried herb tea: 3–9 g per day steeped in hot water (traditional Korean/TCM range). Standardized extract (eupatilin-based): typically 30–60 mg eupatilin per day as studied in clinical settings. Capsule/powder: 500–1,500 mg dried herb equivalent per day. Culinary use has no defined upper limit.
• Best time of day: Digestive support: 20–30 minutes before meals. Menstrual and relaxation support: evenings or as a warm tea before bed. Moxibustion: typically done in the afternoon or early evening in traditional practice.
• With or without food: Tea and liquid extracts are best taken slightly before or between meals for digestive benefit. Capsules can be taken with food to reduce any stomach sensitivity.
• Time to effect: Digestive symptoms: often noticeable within a few days. Menstrual and anti-inflammatory benefits: typically 2–4 weeks of consistent use. Moxibustion effects on joint pain: often felt within 3–6 sessions.
• How long to take it: Traditional use supports ongoing seasonal use (especially spring herb harvest). For targeted therapeutic use (gastritis, menstrual support), 4–8 week courses are common, followed by reassessment. Daily culinary use is considered safe long-term.
