聖約翰草(Hypericum perforatum L., St. John’s wort)為世界上重要之藥草,可用為來舒緩輕到中度的憂鬱症。若能有效調節此藥草之生長及發育階段(例如:開花時間)及提升其主要有效成分之含量,將能大幅提高其生產效率及相關醫藥利用之價值,造福人群。 在本技術為我們利用數種幾種遠紅外線奈米陶瓷粒子(far-infrared-radiated nanopowders of ceramics ),以適當之比例直接或間接添加至栽培介質土壤中,證實可以有效調節此藥草之生長和開花的時間及其主要有效成分金絲桃素(hypericin) 之含量達數倍之多,具有開發利用之潛力。

Far-infrared-radiated (FIR) ceramics with light-emitting properties are known to affect biological functions in animals and humans. The effects of three commercially available FIR ceramics were investigated in Hypericum perforatum (St. John's wart), a herb with widespread use as an antidepressant. Nanopowders were added directly (mixed into cultivated soil mixture), or indirectly (inserted into the spaces between pot and soil mixture). FIR ceramics were shown to influence growth both positively and negatively (P b 0.05) depending on the ceramic and mode of administration. Further, time to flowering was lengthened or shortened to between 63 and 198 days (normal time 135 days). Levels of the bioactive compound hypericin could be increased several-folds in all parts of the plant by treatment with FIR ceramics. We suggest that H. perforatum phytochromes sensitive to red/far-red light are affected by the photodynamic properties of FIR ceramics, leading to changes in biochemical metabolism and flowering time.
