🌿 Folk Prescriptions

Since the Korean drama *Dae Jang Geum* became popular, the fusion of traditional Chinese medicine and cuisine—pharmacological diets—has attracted widespread attention. Many viewers were amazed by the miraculous tonifying and regulatory effects shown in the series. Especially during late autumn and early winter—considered the prime time for physical tonification—many began recording medical techniques and prescriptions from the show, or even incorporating mentioned herbs into daily meals to self-treat. However, the royal pharmacological diets crafted by the character Dae Jang Geum were actually developed by culinary experts based on historical records, and their actual efficacy remains unclear.
Experts caution: although pharmacological diets lack the intense potency of pure herbal decoctions, they still carry the four natures and five flavors of traditional Chinese medicine and have specific suitability. Thus, home-prepared pharmacological diets must not be blindly copied from TV dramas. The show offers only vague descriptions of symptoms for which the diets are intended.
Traditional Chinese medicine has three levels of dietary health: food cultivation (shiyang), food therapy (shiliao), and pharmacological diet (yaoshan). Food cultivation aims to maintain health and strengthen the body through diet. Food therapy and pharmacological diets aim to assist in treating specific illnesses—sharing similar medicinal properties with herbal decoctions, though milder and easier to consume. Therefore, pharmacological diets possess dual attributes: food and medicine. They have cold, hot, warm, cool natures and sour, bitter, sweet, pungent, salty tastes, requiring strict adherence to clinical indications.
The show only vaguely describes symptoms for which the diets are used. For instance, the emperor suffers from neck discomfort, so his physician prescribes ginger. The palace chef prepares a simple late-night meal of ginger and lotus root for him. From a medical perspective, neck discomfort can stem from various conditions—muscle pain from colds, throat pain from coughing, neck pain from bone spurs, etc. Ginger is a warming, yang-enhancing, circulation-promoting herb, typically used for muscle pain due to external cold invasion. Lotus root tonifies the spleen and boosts qi—since the spleen governs muscles—suggesting the emperor’s condition results from external wind-cold. But if viewers experiencing wind-heat-induced sore throat consume ginger, it won’t eliminate pathogens—it may worsen symptoms. Therefore, before replicating any diet from the show, consult professionals to analyze the underlying cause and indication.
Some pharmacological diets yield unpredictable results
Herbal medicine application is complex. First, symptoms must be analyzed to determine the syndrome type—e.g., whether constipation stems from yin deficiency or food accumulation, or whether cough is due to external wind-cold or yin deficiency with dry heat. Second, appropriate herbs must be selected: warm herbs for cold syndromes, cool herbs for heat syndromes, tonics for deficiency, purgatives for excess. Third, herbs must undergo processing before decoction to remove toxicity or enhance potency.
The show fails to warn about processing toxic herbs. Furthermore, diagnostic accuracy is questionable. For example, raw aconite is toxic and must be processed—yet the show uses it in food to treat obesity, raising safety concerns. Also, Dae Jang Geum believes the prince’s feverish body and cold feet indicate qi and blood deficiency—yet in TCM, feverish body with cold extremities typically results from excessive yang heat, stagnant blood flow, and poor peripheral circulation—quite different from qi-blood deficiency. Thus, using the “Yi Gong San” formula to tonify spleen and boost qi would unlikely cure the condition.
Professional guidance is essential for pharmacological diet preparation
From the above analysis, although *Dae Jang Geum* offers many simple, practical pharmacological diet methods, careful scrutiny is still needed. For general viewers, preparing pharmacological diets must involve professional guidance, especially noting:
1. Avoid toxic interactions between herbs. Medicinal effects rely on specific chemical components. If two herbs react during decoction to form toxic substances, they may harm the body instead of curing illness. Common contraindications include: aconite must not be combined with peony, cloves must not be paired with turmeric, ginseng must not be used with five-flavor resin. The “Eighteen Incompatibilities” and “Nineteen Fears” summarize basic herb contraindications.
2. Tailor diets to individual constitution. TCM emphasizes syndrome differentiation. Even identical diseases and syndromes require different treatments based on age, gender, and constitution. Diet formulation must consider personal constitution, health status, disease condition, and seasonal climate. Different constitutions, diseases, and ages require distinct tonification approaches—improper tonification may prolong illness, especially dangerous for elderly, weak, or chronic patients, potentially worsening conditions.
3. Strictly control dosage. With winter approaching, warm, tonifying herbal diets will grow popular. Among these, certain herbs carry toxicity or side effects—use with caution. There have been reports of deaths from poisoning after consuming restaurant-made aconite-ginger lamb stew. Other potentially toxic warm herbs include fine cinnamon and aconite—should be avoided or used only under professional advice. Even non-toxic herbs like danggui and ginseng, if overused or taken long-term, can disrupt yin-yang balance, causing illness or exacerbating existing conditions.
4. Distinguish between herbs with the same name but different properties. Same herbs vary by origin and function—e.g., Fritillaria comes in Sichuan (Chuanbei) and Zhejiang (Zhebei), used for chronic cough and acute wind-heat cough respectively. Ginseng includes red ginseng, sun-dried ginseng, and Korean ginseng—all warm and yang-enhancing; American ginseng is cooler and yin-nourishing. When selecting herbs for pharmacological diets, ask vendors clearly about the herb type, describe your purpose, and seek professional help—never buy randomly from street vendors. Prefer mild, neutral herbs for home preparation
Pharmacological diets incorporate medicinal ingredients into food, allowing herbs to enhance flavor and food to support herb efficacy—maximizing benefits and enabling easy home preparation. However, “medicine carries inherent toxicity”—unless seriously ill, avoid pharmacological diets. Simply maintaining balanced, nutritious diets suffices. If choosing to tonify via pharmacological diets, prefer herbs with mild, bland tastes—less likely to cause harm even with improper dosing. The National Administration of Traditional Chinese Medicine lists 87 herbs safe for food and medicine use, including safer options for pharmacological diets: yam, hawthorn, coix seed, goji berries, lily bulbs, lotus seeds, red dates, ophiopogon, licorice, tangerine peel.
