What happened when you eat a little bit of cork grease?

Eating a small amount of cork grease, which is typically used on wine corks to ease their insertion and removal, is not recommended. While ingesting a tiny amount may not cause serious harm, it could lead to mild gastrointestinal discomfort or an upset stomach. Cork grease is not meant for consumption, so it's best to avoid it altogether. If significant amounts are ingested, it's advisable to seek medical attention.
