Key result
Kidney extracts lower arterial blood pressure, reverse retinal lesions, and increase renal flow in hypertension.
Why the study?
Certain extracts of normal kidneys contain substances that lower arterial blood pressure in hypertensive dogs, rats, and humans, but difficulties in preparation and use remain.
Do extracts of normal kidneys reduce arterial blood pressure in hypertensive dogs, rats, and human beings?
Do extracts of normal kidneys reduce arterial blood pressure in hypertensive dogs, rats, and human beings?
This early progress report suggested that kidney extracts possessed properties capable of lowering blood pressure and improving renal blood flow in experimental and human hypertension.
Answers are grounded in this paper and cite their sources.
Early kidney extracts may lower BP in small hypertensive cohorts; leaves open any therapeutic role pending rigorous trials.

Their administration was also often associated with a rise in the usually depressed renal blood flow.Difficulties both in the preparation of the extract and in its use were numerous....Bibliography1.

Page et al. (1943) studied Hypertension. Kidney extracts was evaluated on Arterial blood pressure, retinal arterial lesions, and renal blood flow. Administration of kidney extracts lowered arterial blood pressure, reversed retinal arterial lesions, and increased renal blood flow in hypertensive dogs, rats, and human beings.
