from the vegetable garden, concerning the curbing of acute fungal attack and other calamities through the horsetail tea liquid manure. Long-term experimental trials on the preventive efficacy of the horsetail preparation do not exist. Controlled trials burst the boundaries of what is practicable. The certainty of efficacy — and this holds for all the preparations named — is the conceptual penetration of the results of spiritual-scientific research, together with the confirming experience that practice teaches.
