The invention relates to the use of a humic acid-containing substance in medicine, to pharmaceutical compositions containing as active ingredient such a substance, and to a process for preparing this substance. The humic acid-containing substance according to the invention is preferably used in the form of a pharmaceutical composition containing 0.01 to 99.90 % by weight of humic acid-containing substance of peat origin as active ingredient together with carriers and/or other known additives. The invention also relates to a process for the preparation of a humic acid-containing substance of peat origin, which comprises using as the starting material a juvenile, preferably at most 10,000 years old, peat formed from a great bulrush and winter-sedge as peat-forming plants; preparing a suspension by stirring the peat with an aqueous alkaline solution of pH 7.5 to 10.5; utilizing the upper phase of the obtained suspension by adjusting its humic acid content to 10-100 g/L; concentrating it; or bringing it into solid form by dehydration. |
