Q. I've heard the perilla oil diet is great for health. From a Korean medicine perspective, what’s the best way to start?

While the perilla oil diet is popular, jumping in without preparation can lead to digestive distress. From a Korean Medicine perspective, here is a four-step guide to succeeding healthily. First, check for 'Spleen Deficiency' (脾虛). If your Spleen function is weak and your digestive power is low, consuming raw oil can be a significant burden. If you frequently experience loose stools or abdominal sounds (borborygmus), taking oil on an empty stomach may cause internal upset. Such individuals must have an adaptation period, starting with very small amounts. Second, use the morning fasting period as a 'priming' phase. We recommend taking it when the body's Qi (energy) is first waking up. This can gently stimulate the intestines to relieve constipation and act as a catalyst for discharging 'Blood Stasis' (瘀血)—the stagnant, pathological blood waste in the body. Third, you must be strict about freshness and storage. In TKM, rancid oil is a primary culprit that creates more 'Phlegm-Fluid' (痰飮), which are non-physiological metabolic wastes. Always refrigerate the oil and purchase small amounts of freshly pressed oil frequently to ensure you are consuming it at its peak. Finally, the effects are significantly enhanced when combined with constitution-specific herbal medicine. While perilla oil is an excellent supplement, it has clear limits if your metabolism is already compromised. A prescription from a Korean medicine clinic that improves 'Qi and Blood circulation' can act as the foundational 'groundwork,' making weight loss proceed much more smoothly—much like oiling a creaky machine. Ultimately, the key is whether your body is ready to accept this oil. Rather than simply following a trend, I recommend starting slowly while monitoring your digestive state.
