No: If you have black, tarry malodorous stool please seek prompt medical attention for possible GI bleeding.

See your doc: Black stools can be from gastrointestinal bleeding (usually upper GI source), iron pills, peptobismol, charcoal capsules, arsenic. Dark stools can also come from blueberries, etc. See your doc. See if stool tests + for blood. If so get evaluated-generally upper endoscopy, maybe colonoscopy (black stool can be from right side of colon), or capsule endoscopy to check small bowel.
