The Salt Lake mineral was dissolved in the warm water to develop bath salt that contained the Salt Lake mineral with the element of seawater, and we made comparative study of the effects with the tap warm water for five healthy adults.
As a result, the warm water with the Salt Lake mineral increased in the changes of the surface skin temperature in the forehead, the deep thermometer in front of chest and the tissue blood flow of thigh skin compared to the tap warm water.
Therefore, the warm water with the Salt Lake mineral was suspected that the thermo effects was good compared to the tap warm water.
It seemed that it was possible to use it safely as bath salt, for it did not change the blood pressure, the heart rate, the oxygen uptake and carbon dioxide exhaust. Also, the abnormality of the skin was not additionally recognized.

We evaluated the effects of SCP bathing on the body by compared with those of a-EG, one of major component of SCP, bathing and the control bathing with tap water alone. Healthy adults were used as the subjects. The effects of bathing on blood pressure and pulse rate were not significantly different among the three bathings, indicating that effects of SCP and α-EG bathing on the lung and heart were similar to those of an ordinary bathing. The surface skin temperature at the forehead decreased more slowly in the subjects after taking a SCP bathing than the other two, suggesting that SCP has temperature holding effects. Also, the results of deep body temperature suggested that α-EG might be related to the heat absorbing effects of SCP bathing, which were significantly marked than those of the other two bathings. The present results regarding the changes in blood flow and deep body temperature during bathing suggest that SCP might produce an environment that allows more rapid heat transfer from bath water to the body and less releasing it from the body. Therefore, we concluded that some component other than α-ethylglucoside would be involved in the heat transfer and moisturizing during SCP bathing. Measurement of skin water content indicated that a region directly contacting with hot water was moisturized in a short time, but this condition quickly returned to the pre-bath condition. Whereas, for regions not contacting with bath water, the skin was much more moisturized by taking SCP bath than the other two bathings. Therefore, it was concluded that SCP is effective for enhancement of skin moisturizing.

Ginseng powder was dissolved in the warm water to develop bath salt that contained Ginseng powder (250mg: 1% Ginseng powder, 500mg: 2% Ginseng powder) and it made comparative study of the effects with the tap warm water for seven healthy adults (male 3, female 4, 20.7±0.8 years old). The Ginseng powder of 250mg and 500mg was made so that the bath salt of 25g may become 1% and 2%. The whole body immersion of 15 minutes was done to all subjects under the condition that 1% or 2% cannot be distinguished without tap water bathing.
As a result, the warm water with Ginseng powder increased in the changes of the deep thermometer in front of chest between immersion and after bathing, compared with the tap warm water. But there were not significant change of the surface skin temperature on the arm and the tissue blood flow on thigh skin.
Therefore, the warm water with Ginseng powder was suspected that the thermo effects and the retaining warmth were good compared with the tap warm water.
It seemed that it was possible to use it safely as bath salt for it did not change of the blood pressure, the heart rate, and abnormality of the skin without the case to whom the skin had temporarily flushed, was not additionally recognized.
