Track Coffea Cruda (30C) with reminders and record whether it helped, in the app.
Coffea Cruda is a classical homeopathic remedy prepared from raw, unroasted coffee beans through a process of serial dilution and succussion (vigorous shaking), diluted to the 30C potency — meaning the original substance has been diluted far beyond the point where any caffeine molecules remain. In homeopathic philosophy, this extreme dilution is thought to leave behind an energetic 'imprint' of the original substance. It is one of the most widely used over-the-counter homeopathic sleep remedies, particularly popular in Europe, India, and among homeopathic practitioners globally.
Homeopathy operates on the principle of 'like cures like' — a substance that causes symptoms in a healthy person can, in highly diluted form, relieve similar symptoms in someone who is unwell. Coffee in large amounts causes wakefulness, racing thoughts, and sensory hypersensitivity; Coffea Cruda in homeopathic form is therefore used to address those exact symptoms. From a conventional pharmacology standpoint, no active molecules are present at 30C, so any observed effects are attributed by proponents to the homeopathic 'vital force' response rather than biochemical action.
Most commonly available as small sublingual lactose pellets (globuli) in 30C potency — the standard over-the-counter homeopathic potency for acute complaints. Also available as liquid dilutions in water-alcohol base or as compressed lactose tablets. Pellets are dissolved under the tongue away from food, strong flavors, or aromatic substances, per homeopathic protocol.
Coffea Cruda was introduced into the homeopathic materia medica by Samuel Hahnemann himself in the early 1800s. Hahnemann noticed that coffee produced a state of heightened mental and sensory excitability, and on homeopathic principles, included it as a remedy for states of nervous overstimulation, insomnia, and acute pain with hypersensitivity. It has remained a staple of classical homeopathic practice for over 200 years and is consistently listed in homeopathic repertories under sleep disorders and nervous complaints.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Coffea Cruda (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.
