Any deficiency or excess of vital elements will cause this or that disease. And it’s good when empirical knowledge is confirmed by scientific methods. For example, research engineers of the 1st category L. Bobrova and G. Astrovskaya by the method of atomic emission spectroscopy on a certified laser elemental analyzer LEA-S500, produced by our company, studied 9 macroelements and 15 microelements in 9 different mixtures of herbs provided by E. Shmerko. State standard samples were taken as a basis. And in the sedative mixture, a high content of magnesium, lithium, and rubidium was found, in the kidney mixture – silicon and potassium, in the anti-inflammatory mixture – calcium, silicon, phosphorus, potassium, sodium, copper, and in the liver mixture – iron. Thus, studies have once again confirmed that herbs are a good, reliable and proven source of macronutrient and micronutrient intake.
