Discover how substances travel through the body and keep their active powers.
This work presents a controversial view that certain medicines and foods enter the bloodstream in active form and can be reconstituted or recomposed in circulation. Drawing on observations from urine, milk, saliva, sweat, and even flesh and skin, the text builds a case that what we ingest can influence distant tissues just as directly as if applied where symptoms appear.
Through a sequence of sections, the author surveys the evidence for circulation-based effects, including the appearance of medicinal and culinary substances in fluids like milk and perspiration. The discussion weaves together classic examples, practical implications, and cautions about external applications of poisons, aiming to offer a unified view of how substances traverse and act within the body.
- Examine how elements pass from food, medicines, and even certain plants into the bloodstream and beyond.
- Learn how milk, saliva, and perspiration can carry active properties from the source to distant sites.
- Explore historical experiments and natural observations that support the central claim.
- Consider the safety and clinical implications of measuring and understanding these circulatory effects.
Ideal for readers curious about early ideas on pharmacology, physiology, and the science of how ingested substances affect the whole body.
