According to Eastern wisdom, the green hue of lime links it to the liver. Its sour and slightly sweet flavor helps transform dampness, while its mildly cooling nature promotes dispersion. It is believed to soothe the liver and relieve stagnation, as well as to transform phlegm with its aromatic properties. Entering the liver and spleen meridians, lime is said to uplift the spirit, awaken the spleen to stimulate appetite, and alleviate fatigue and mental exhaustion. Moreover, its high concentration of limonene is thought to help cleanse the body. When used as a diffuser, it purifies the air; in skincare products, lime is commonly employed to balance sebum production, assist in cleansing, and brighten the complexion—its refreshing aroma also serving to elevate the mood.
