Q. Yes, but you didn’t quite answer my question. I inquired about the individual doses.
A. Yes, well, I’m trying to say that if you spread it out over a day, giving smaller individual doses instead of giving it all at once, then there isn’t any danger of diarrhea.
Q. Can you describe sea-water as poisonous at all?
A. Absolutely not. There is a trend towards treatment with sea-water which is increasing, and people drink half a liter of sea-water every day for weeks. There can’t be any question of any poisonous quality. In fact, people say they feel splendid. The only difference is that in the case of such cures fresh water is administered, too, in the manner of tea, coffee, and soup, so that the dehydrating effect of the sea-water is counteracted.
Q. Professor, I wonder if you would speak a little more slowly and make a pause after individual answers in order to enable the interpreters to follow.
Has there been an experiment during which a dose of 500 to 1,000 cc. of sea-water daily was taken and is it to be described as dangerous, providing the experiment is discontinued as soon as there is a threat of danger to health?
A. There can’t be any question of there being any danger to health during the first few days. The only question is, how long can the body stand up to this continued deprivation of humidity? Sea-water has a three-percent salt water content. Generally speaking, at least so far, we have assumed that the kidneys cannot deal with such a salt concentration. This means that salt will remain in the system, collecting water from the tissues. In the beginning, this is of no importance, but after 6 or 7 or 8 days, this becomes unpleasant and it is to be expected that after the twelfth day there is some danger. There have been cases of sea rescue when even 17 or more days afterwards recovery was achieved, but I would say that I would never dare to continue such an experiment beyond the twelfth day, and in this case with which we are concerned, all experiments were discontinued after the sixth day, so that danger to health during that period was out of the question.
Q. Could the aim of these experiments have been achieved with a semipermeable membrane?
A. I don’t understand how one can imagine this. What we are concerned with is the question of how long the human body can survive without water and under the excess quantity of salt. Now, that is subject to the water content of the body and it depends first of all, upon whether water is only used by the intermediary tissues or whether the cell liquid too is being used up. In the latter case, there is a danger which becomes apparent through excess potassium quantities, and this was also continuously observed and checked during such experiments, and there were no excess potassium quantities such as can be expected after 6 days.
Q. Nor would it be right to say that these experiments were not planned scientifically and medically, is that correct?
