The desire to use natural remedies for your baby's teething is understandable. You want to minimize medication, avoid chemicals, and use gentle approaches. There is nothing wrong with this instinct — as long as it is paired with critical evaluation of what is actually safe and effective.
The problem is that the "natural teething remedy" space is largely unregulated. Products can be marketed as natural, herbal, or homeopathic without proving they are safe or effective. Some are genuinely harmless (coconut oil on gums). Some are actively dangerous (clove oil, belladonna tablets, amber necklaces). And the labeling rarely makes the distinction clear.
A useful framework: Does this remedy work through a mechanism that makes sense (cold reduces inflammation, pressure modulates pain)? Is there evidence it is safe for infants? Has any regulatory body issued warnings about it? If the mechanism is implausible, the safety data is absent, or there are regulatory warnings, skip it — regardless of how "natural" the marketing says it is.
