Belladonna 30C is a homeopathic preparation derived from the Atropa belladonna (deadly nightshade) plant. It is prepared through a process of serial dilution and succussion (vigorous shaking) — repeated 30 times in a 1:100 ratio — resulting in a remedy that contains no detectable alkaloid molecules from the original plant. It is one of the most widely used remedies in classical homeopathy, particularly for acute conditions. The remedy is governed by homeopathic principles rather than pharmacological ones, and its mechanism of action — if any — remains scientifically unexplained.
According to homeopathic theory, Belladonna 30C works on the principle of 'like cures like' — that a substance capable of producing symptoms in a healthy person can, in extreme dilution, stimulate the body to resolve similar symptoms. The 30C dilution is so extreme that standard chemistry finds no measurable active compound; homeopaths argue that water retains a 'memory' or energetic imprint of the original substance. Conventional science does not accept this mechanism, and the remedy's effects, where observed, are not distinguishable from placebo in most controlled trials.
Most commonly available as small sucrose or lactose pellets that dissolve under the tongue. Liquid preparations (drops) and compressed tablets are also available. Pellets are the traditional and most popular form for acute use.
Atropa belladonna has a long and complex history in European medicine — used as an anesthetic, cosmetic (Renaissance women used it to dilate pupils), and poison. Samuel Hahnemann, the founder of homeopathy, was one of the first to document its homeopathic use in the early 1800s, including its application in treating scarlet fever epidemics. It remains one of the foundational ('polychrest') remedies in classical homeopathy worldwide.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Belladonna (30C) is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
