• The number and speed of radiogram receptions for radiotelegraphic operators was increased with daily doses of 1 1/2 droppersful (60 drops) of a liquid extract of eleuthero over a one-month period.
• Skiers taking a single dose of eleuthero extract (3 droppersful) before a race experienced increased resistance to the harmful effects of the cold and increased physical endurance, especially if the skier was not fully trained.
• Workers in a publishing house who had jobs involving physical labor showed enhanced cardiovascular output, ability to work, and improved appetite--without hypertension. However, the extract was not recommended for people with blood pressure over 180/90 mm Hg.
• Proofreaders were more effective in their work after taking 1 1/2 droppersful of eleuthero extract daily for 30 days.
• Sailors who took eleuthero extract while on long sea voyages showed improved work capability and normalization of body functions in high-temperature conditions.
• One thousand factory workers in a city of the polar region who took 3 droppersful of eleuthero extract daily showed 50% reduction in general sickness and 40% reduction in the number of lost work days.
• Among truck drivers who took eleuthero extract in tea for six years, the total number of people contracting influenza dropped from 41.8% to 2.7% during that period, and the number of work days lost to influenza per year dropped from 286 per 100 workers to 11.
• Other studies showing that eleuthero dramatically reduced the number of sick days due to influenza among thousands of different kinds of workers are reported.
• Further studies show that eleuthero extract, when taken on a regular basis, can improve visual acuity, color perception, and hearing acuity, can increase the efficiency of people whose jobs require attention and cause nervous tension, and can improve physical and mental working capacity under unfavorable climatic conditions (i.e., too hot, too cold, high altitude, etc.).

Sick Volunteers

• Forty-five volunteers with heart disease showed enhanced feelings of well-being, fewer chest pains, reduced blood pressure and cholesterol levels, and improved ECG readings after six to eight courses (25 days each) of eleuthero extract (1 to 1 1/2 droppersful at a time, 3 times daily before meals).In a second study on 65 patients with cardiovascular disease, with the same dose as above, improvements were noted by some after the first course (25-35 days).
• Several studies involving patients with diabetes showed that in some cases eleuthero extract is effective in lowering serum glucose levels.
• People with both hypotension and hypertension showed normalization of blood pressure after courses of eleuthero extract. Several other studies support these findings.
• Fifty-eight people with psychological imbalances and symptoms such as extreme exhaustion, irritability, insomnia, decreased work capacity, and a general state of anxiety, showed improvement after taking 2 droppersful of eleuthero extract, once in the morning and once in the evening, for four weeks. The patients felt that sound sleep and an increase in their sense of well-being were the most important benefits of the treatment.
• Five more studies with nearly 160 neurotic patients showed that eleuthero extract (as little as 1 dropperful a day) can be of benefit as indicated above. Some of the studies lasted for ten years.
