The perilla oil diet focuses on the power of 'healthy fats' to transform metabolism. Alpha-linolenic acid, the primary component of perilla oil, directly stimulates genes responsible for fat burning. From a Western medical perspective, it is known to lower blood cholesterol and reduce inflammation, which helps improve metabolic syndrome. In Traditional Korean Medicine (TKM), perilla oil is highly regarded for its ability to eliminate Phlegm-fluid (Dam-eum) and Blood Stasis (Eohyeol). Phlegm-fluid refers to metabolic waste formed from stagnant body fluids, while Blood Stasis is a condition where blood clumps and hinders healthy flow. When these toxins accumulate, they block the circulation of Qi and Blood, creating a constitution that gains weight easily. Perilla oil lubricates the intestines and purifies the blood to facilitate the discharge of these toxins. This approach is particularly beneficial for individuals with Spleen Deficiency (Bi-heo), who often suffer from poor digestion or frequent edema (swelling). Perilla oil protects the intestinal mucosa and naturally aids bowel movements. However, since it is still a calorie-dense fat, overconsumption can lead to adverse effects like diarrhea. It is important to consult with a practitioner to ensure it suits your specific constitution.
