应用姜氏生物场导仪，对１５名志愿者用同体对照法观察了植物幼苗生物场对人体血清性激素浓度的影响。其中７名女性检测了血清孕酮浓度，结果是场导后均比场导前显著升高（Ｐ＜０．０５），但多不超出正常值的最高限。其中８名男性检测了血清睾酮浓度，结果是场导后也都比场导前显著升高（Ｐ＜０．０１），但也不超出正常值的最高限。本研究结果支持植物幼苗生物场对人体具有抗衰老作用。 The effects of plant seedling biological field on human serum sex hormones were observed in 15 volunteers using the ginger bio-meter. Seven of the women tested for serum progesterone concentrations, which were significantly higher (P <0.05) than those in the field guidance after field conduction but did not exceed the upper limit of normal. Serum testosterone levels were measured in eight men and the results were significantly higher (P <0.01) than before field guidance but not beyond the upper limit of normal. The results of this study support the plant seedling biological field has anti-aging effect on the human body.
