A pogostemon cablin cultivation method comprises the steps of: (A) providing pogostemon cablin with light illumination for at least eight hours on a daily basis, in which the light illumination is a kind of light ray illumination providing wavelength of 440nm to 480nm and 620nm to 660nm and (B) soaking the pogostemon cablin in a liquid fertilizer for eight hours to twelve hours while providing the pogostemon cablin with the light illumination, in which the liquid fertilizer comprises nitrogen with a concentration of 100ppm to 243.75ppm, phosphorus with a concentration of 100ppm to 200ppm, and potassium with a concentration of 100ppm to 200ppm. Accordingly, with the disclosed pogostemon cablin cultivation method, the cultivated pogostemon cablin can have a large-sized leaf in average and a high content and concentration of carvacrol, i.e., an excessive concentration is not required.一種左手香培育方法包含步驟A:以日為單位,提供左手香至少8小時的光照,所述的光照是提供波長為440nm至480nm及620nm至660nm的其中一種的光線照射。步驟B:在提供左手香光照的同時,使左手香於液態肥料中浸泡8小時至12小時。該液態肥料包括濃度為100ppm至243.75ppm的氮、100ppm至200ppm的磷,以及100ppm至200ppm的鉀。本發明所培育出來的左手香的葉子的平均葉徑較大,除香芹酚的含量較高外,濃度也較高,無需過度濃縮,即可直接添加於保健用品中。
