Chemotherapy Dysgeusia & Miracle Berry Research

Chemotherapy and radiation treatment can sometimes change the way food tastes. This is commonly called dysgeusia or, more casually, “chemo mouth.” Some people describe foods as metallic, bitter, bland or unpleasant, which can make eating harder during treatment.

Miracle berry, also known as Synsepalum dulcificum, has been discussed in scientific literature, clinical research and media coverage for its temporary taste-modifying effect. Below are selected links for people who want to learn more.
