Coffea cruda is a homeopathic preparation produced from green (unroasted) coffee beans. Homeopathy is an alternative medicine system created roughly 200 years ago by the German physician Samuel Hahnemann. Its practice rests on two principles that lack scientific support:
- Principle of similarity. An illness can be remedied with a substance that produces comparable symptoms in healthy individuals. For instance, since coffee is a stimulant, some homeopaths contend that Coffea cruda might help people who are overstimulated.
- Law of minimum dose. The smaller the dose of a treatment, the greater its therapeutic power.
Even though evidence is lacking, some individuals believe Coffea cruda can be used for a range of complaints such as:
- attention deficit hyperactivity disorder (ADHD)
- pain
- trouble falling asleep
- mental overactivity
- headaches
- toothaches
Overall, there is little to no reliable evidence that homeopathy is an effective medical treatment. The handful of studies suggesting possible benefits of Coffea cruda:
- are experiments in animals
- include small sample sizes
- show conflicts of interest
- often have poor methodology and a high risk of bias

Medicinal claims for Coffea cruda
Homeopathy advocates claim people who are nervous, overstimulated, excitable, or hypersensitive might gain from Coffea cruda.
The rationale is tied to the homeopathic “principle of similarity”: because consuming coffee can produce nervousness and heightened arousal, a homeopathic preparation of coffee could, in theory, treat symptoms of overstimulation or nervousness.
However, there is no scientific data to substantiate this reasoning for Coffea cruda or any other homeopathic product.
After a comprehensive review of the literature, the Australian National Health and Medical Research Council concluded that there is no dependable evidence supporting homeopathy as an effective treatment for any health condition.
The European Academies’ Science Advisory Council reached a similar verdict after reviewing the evidence: homeopathy is not effective for treating diseases and its purported mechanisms are inconsistent with established scientific understanding.
Concerns about Coffea cruda supplements
Coffea cruda originates from unroasted coffee beans, so in principle it could contain compounds found in coffee, such as caffeine and the antioxidant chlorogenic acid, which have plausible biological effects.
In practice, Coffea cruda marketed as a homeopathic remedy is typically diluted many millions of times in water or alcohol. Many items are so attenuated that no trace of the original coffee substance remains.
Homeopathic product strengths are commonly indicated with an “X” or “C.” You’ll often see products labeled between “6 X” and “30 X” or “6 C” and “30 C.”
“X” denotes successive dilutions at a 1:10 ratio.
For example:
| Dilution | Amount of Coffea cruda | Amount of water or alcohol |
| 1 X | 1 tsp | 10 tsp |
| 2 X | 1 tsp | 100 tsp |
| 3 X | 1 tsp | 1,000 tsp |
| 4 X | 1 tsp | 10,000 tsp |
| 5 X | 1 tsp | 100,000 tsp |
| 6 X | 1 tsp | 1,000,000 tsp |
A product diluted to 30X would contain one teaspoon of Coffea cruda per nonillion (a 1 followed by 30 zeros) teaspoons of diluent.
“C” indicates dilutions in a 1:100 ratio. A teaspoon of “6 C” Coffea cruda would be mixed with a trillion teaspoons of solvent; a 30 C product would be diluted to one teaspoon of Coffea cruda per novemdecillion (a 1 with 60 zeros) teaspoons of water or alcohol.
Common uses of Coffea cruda
There are no high-quality human trials demonstrating that Coffea cruda effectively treats any medical disorder; apparent benefits are most likely attributable to placebo effects.
Coffea cruda for anxiety and mood
A low-quality 2010 trial explored whether two homeopathic remedies, nux vomica and Coffea cruda, altered self-reported mood in adults experiencing coffee-induced insomnia.
Researchers reported that 30 C Coffea cruda reduced subjective tension in anxious participants and increased tension in those classified as hostile.
However, the study’s methodology carries a high risk of bias. Outcomes were subjective and the study lacked an adequate control group.
Coffea cruda for ADHD
There is no credible scientific evidence that Coffea cruda treats ADHD.
Coffea cruda for sleep
There is no persuasive proof that Coffea cruda helps people fall asleep faster or improves sleep quality.
A 2012 study reported alterations in sleep-related EEG patterns in a group of 54 college students after taking Coffea cruda, but this provides very weak evidence that the remedy produced the effect.
- Participants were required to abstain from coffee before the trial, which could have influenced results
- There was no control group for comparison
- The lead investigator served as a consultant for Standard Homeopathic Co./Hyland’s Inc., presenting a conflict of interest
Side effects and safety considerations
Coffea cruda is unlikely to produce side effects because it is typically extremely diluted. Homeopathic remedies are not FDA-approved, and their manufacturing is not held to the same regulatory standards as conventional medicines, so products can sometimes contain undeclared or harmful substances.
Additionally, Coffea cruda formulations may include non-medicinal components such as grain alcohol or lactose, which can trigger allergic reactions or other adverse responses in susceptible individuals.
FDA stance on homeopathic products
There are no FDA-approved homeopathic products. Items promoted as homeopathic remedies have not undergone FDA evaluation for safety or effectiveness.
Although often marketed as natural and safe, homeopathic products may contain undisclosed and potentially dangerous ingredients; they should be used only after consulting a healthcare professional.
Takeaway
Coffea cruda is a homeopathic preparation made from unroasted coffee beans. Current research has not found reliable evidence that it effectively treats any medical condition. Most Coffea cruda products are diluted millions of times in water or alcohol, frequently to the point where no original substance can be detected. If you’re considering alternative treatments or topical options such as a coffee scrub for cellulite, discuss them with your healthcare provider to ensure safety and appropriateness.
