Crystal healing is a pseudoscientific alternative-medicine practice that uses semiprecious stones and crystals such as quartz, agate, amethyst or opals. Adherents of the practice claim that these have healing powers, but there is no scientific basis for this claim.
Crystal Healing - How It Works
Grounding is currently an under-researched topic and there are very few scientific studies on the benefits. However, the most recent scientific research has explored grounding for inflammation, cardiovascular disease, muscle damage, chronic pain, and mood.
The central theory from one review studyTrusted Source is that grounding affects the living matrix, which is the central connector between living cells.
Electrical conductivity exists within the matrix that functions as an immune system defense, similar to antioxidants. They believe that through grounding, the natural defenses of the body can be restored. Further research expands on this idea.
In a small studyTrusted Source on grounding and heart health, 10 healthy participants were grounded using patches on the palms of their hands and soles of their feet.
Blood measurements were taken before and after grounding to determine any changes in red blood cell fluidity, which plays a role in heart health. The results indicated significantly less red blood cell clumping after grounding, which suggests benefits for cardiovascular health.
Another slightly larger studyTrusted Source examined the role of grounding on post-exercise muscle damage. Researchers used both grounding patches and mats and measured creatine kinase, white blood cell count, and pain levels before and after grounding.
Blood work indicated that grounding reduced muscle damage and pain in participants. This suggests that grounding may influence healing abilities.
This research is supported by a recent studyTrusted Source on grounding for pain reduction and mood improvement. Sixteen massage therapists alternated between periods of grounding and no grounding.
Before grounding therapy, physical and emotional stress and pain were common side effects of their physically demanding jobs. After the earthing therapy, pain, stress, depression, and fatigue were all reduced among participants.
Most of the studies on grounding are small and rely somewhat on subjective measures, such as self-reported feelings, mood, or even self-administered treatment.
Some studies also rely on blood markers, such as those that detect inflammation, but the size and shortage of these studies suggests that more research is needed.
