Methodology

dolor-reishiSixty-six patients affected by FM from different cities of Spain were subjected to a randomized double-blind clinical trial.

The experimental group received 3 grams of microground powdered reishi twice a day for six weeks (once at breakfast and once at dinner) while the other group was given the same quantity of an active placebo.

An initial measurement, prior to the treatment with reishi, and a final measurement after 6 weeks of treatment were made; a follow-up measurement was carried out 3 weeks after the end of the treatment.

Each measurement consisted of: questionnaires regarding Health Related Quality of Life (HRQOL), a test to measure physical condition and pain.

Results

According to the results of the study, the group that took reishi improved the following aspects with respect to those that did not take it:

1. Inability, evaluated with the fibromyalgia impact questionnaire (FIQ). People who took reishi had a greater ability to perform their daily tasks at home and at work (such as shopping, etc).

2. Sleep, evaluated through the Health Related Quality of Life (HRQOL) questionnaire. People who took reishi were able to sleep better.

3. Happiness, assessed using the general happiness scale that measures the degree of happiness from 1 (not happy) to 7 (very happy). After taking the reishi the people felt happier, possibly due to the sleep and symptoms improvement.

4. The global clinical scale, a scale that evaluates the degree of improvement from 1 (much better) to 7 (much worse). After the treatment, the people who took reishi felt better with respect to those who did not take it.

5. Aerobic resistance, speed and flexibility of the lower limbs, assessed by means of the 6-minute walking test, after walking 20 meters at maximum speed, sitting on a chair and trying to reach beyond the tip of the foot.

In addition, the results of the study have shown that reishi could be effective in reducing:

1. Degree of pain, assessed through an analog scale of pain.
