The minimum dose refers to the smallest amount of a substance that can produce a measurable effect in a living organism. The specific minimum dose of a substance can vary depending on various factors such as the individual’s age, weight, health status, and sensitivity to the substance.

In medicine, the minimum effective dose (MED) is the lowest dose of a medication that provides the desired therapeutic effect in most people. It is important to determine the MED of a drug to avoid overmedication and reduce the risk of side effects.

In toxicology, the minimum toxic dose (MTD) is the lowest dose of a substance that produces adverse effects. The MTD is used to determine the level of exposure that is considered safe for humans and animals.

Homeopathy is a form of alternative medicine that uses highly diluted substances to treat various ailments. The principle of homeopathy is that “like cures like,” meaning that a substance that can cause symptoms in a healthy person can be used in a highly diluted form to treat those same symptoms in a sick person.

In homeopathy, the minimum dose refers to the idea that the more diluted a substance is, the more powerful its healing properties become. Homeopathic remedies are often diluted to the point where there is little or no trace of the original substance left.
Proponents of homeopathy argue that the energetic imprint of the original substance remains, even at high dilutions, and that this imprint can stimulate the body’s own healing mechanisms.
