What Does Soap Taste Like in the Mouth?

February 14, 2024

Soap is a detergent that consists of fats, lye & additives for color & fragrance. It’s not uncommon for soap to have a unique taste all its own (think: neem soap). A strange taste or sensation in the mouth usually doesn’t mean that something serious is wrong. It may be as simple as a medication causing a soapy or metallic taste in the mouth. If that’s the case, talk to your physician to determine the cause.

Cilantro (aka coriander) is a popular herb in many cuisines – to some people, however, it tastes like soap. This odd phenomenon is actually due to a genetic variation that causes some individuals’ taste buds to perceive a strong soapy-like flavor in cilantro. Other factors that can affect your mouth’s taste include acid reflux, dental conditions, oral thrush & dry mouth. Medications & dietary supplements may also cause a change in your sense of taste, so it’s always best to consult with your doctor first.

In rare cases, a persistent soapy taste in the mouth can indicate poisoning from sodium fluoride exposure or methyl bromide (a pesticide). If the unpleasant flavor persists for more than a few days or is accompanied by additional symptoms like dilated pupils, spasms, vomiting or diarrhea, you should seek emergency medical attention immediately & contact your local Poison Control center for further guidance, advises Medical News Today.
