Coffea cruda is a homeopathic remedy made from unroasted coffee beans. Homeopathy is a form of alternative medicine developed about 200 years ago by German doctor Samuel Hahnemann. It’s based on two principles not supported by science:

  • Principle of similarity. A disease can be cured with a remedy that produces similar symptoms as a condition in healthy people. For example, coffee is a stimulate so some proponents of homeopathy believe Coffea cruda can help treat people who are overstimulated.
  • Law of minimum dose. The lower the dose of a treatment, the greater its effectiveness.

Despite a lack of evidence, some people believe that Coffea cruda can treat a variety of conditions like:

There’s little evidence to no evidence to support homeopathy as an effective medical treatment. The few studies that have found potential benefits of Coffea cruda:

  • are animal studies
  • have limited sample sizes
  • have conflicts of interest
  • have a poor study design with a high risk of bias

According to proponents of homeopathy, people who are nervous, overstimulated, excitable, or hypersensitive may benefit from taking Coffea cruda.

Coffea cruda’s ability to treat these conditions is based on the homeopathic “principle of similarity.” Or, in this case, the idea that because coffee can cause nervousness and excitability when ingested, it may be able to treat symptoms related to overstimulation or nervousness.

But there’s no scientific evidence to back this logic for Coffea cruda or any other homeopathic remedy.

After performing a large review of studies, the Australian National Health and Medical Research Council found no reliable evidence that homeopathy is effective at treating any condition.

After performing their own review of studies, the European Academies’ Science Advisory Council also came to the conclusion that homeopathy isn’t effective at treating any disease. They also released a statement: “The claims for homeopathy are implausible and inconsistent with established scientific concepts.”

The problem with Coffea cruda supplements

Coffea cruda is derived from unroasted coffee beans. In theory, it could contain all the active ingredients in coffee, like caffeine and the antioxidant chlorogenic acid, that have known or plausible effects on human health.

But Coffea cruda sold as a homeopathic supplement is often diluted millions of times in water or alcohol. Many products are so diluted that no Coffea cruda can actually be detected.

When you buy homeopathic supplements, you’ll see the strength listed with an “X” or “C”. Products are often sold in the range of “6 X” to “30 X” or “6 C” to “30 C.”

“X” refers to how many times it has been diluted with water in a 1:10 ratio.

For example:

DilutionAmount of Coffea crudaAmount of water or alcohol
1 X1 tsp10 tsp
2 X1 tsp100 tsp
3 X1 tsp1,000 tsp
4 X1 tsp10,000 tsp
5 X1 tsp100,000 tsp
6 X1 tsp1,000,000 tsp

A product diluted to 30X would have 1 teaspoon of Coffea cruda per nonillion (a 1 with 30 zeros behind it) teaspoons of water or alcohol.

“C” refers to how many times the product has been diluted with water in a 1:100 ratio. A teaspoon of “6 C” Coffea cruda would be diluted with a trillion teaspoons of water. A 30 C product would be diluted to 1 teaspoon of Coffea cruda for each novemdecillion (a 1 with 60 zeros) of water.

No high-quality human studies support the idea that Coffea cruda can effectively treat any medical condition or that its effects come from anything other than the placebo effect.

Coffea cruda for anxiety and mood

A low-quality 2010 study examined whether the two homeopathic remedies nux vomica and Coffea cruda could change subjective mood ratings in adults with coffee-induced insomnia.

The researchers found 30 C of Coffea cruda decreased subjective tension in anxious subjects and increased feelings of tension in hostile subjects.

But the design of the study has a high risk for bias. Measurements used in the study were subjective, and there was no control group.

Coffea cruda for ADHD

There’s no scientific evidence that Coffea cruda can treat ADHD.

Coffea cruda for improving sleep

There’s no compelling evidence that Coffea cruda can help you fall asleep faster or improve your sleep quality.

A 2012 study found a group of 54 college students had changes in sleep brain waves measured with an electroencephalogram (EEG) after taking Coffea cruda. But the study provided very low-quality evidence that Coffea cruda directly caused the change.

  • the participants all had to eliminate coffee before the study, which could affect the results
  • there was no control group
  • the lead researcher was a consultant for the company Standard Homeopathic Co./Hyland’s Inc.

Coffea cruda is unlikely to cause side effects since it’s usually highly diluted. Homeopathic products aren’t FDA-regulated, so they can potentially contain dangerous ingredients not on the label.

Coffea cruda may also contain non-medical ingredients like grain alcohol or lactose that may cause an allergic reactions in some people.

FDA-regulation of homeopathic products

There are no FDA-approved homeopathic products. Products marketed as homeopathic remedies haven’t gone through FDA evaluation for safety or effectiveness.

Despite often being marketed as safe and natural, homeopathic products can contain potentially dangerous ingredients not listed on the label and should only be used after speaking with a doctor.

Coffea cruda is a homeopathic supplement made from unroasted coffee beans. Research hasn’t found any evidence that it’s effective at treating any medical conditions. Coffea cruda products are usually diluted millions or more times with water, often to the point where no active ingredient can be detected.
