Purple Tongue Due to Blood Circulation Issues:
When the blood fails to deliver sufficient oxygen to the body, then it can also cause a purple or bluish tongue. The condition of bluish discoloration of the tongue or the purple tongue is termed as cyanosis.

Anemia also causes Vitamin B2 deficiency, which in turn causes purple tongue. There can also be swelling of the tongue along with purple discoloration of tongue in vitamin B2 deficiency.
Other than purplish tongue, other symptoms of a vitamin B2 deficiency consist of: mouth sores, fatigue, cracked lips, skin inflammation and changes in the mood.
Bacteria Causing Purple Tongue:
There are thousands of bacteria found on the tongue and in our mouth. Some of them are good bacteria, which are needed for good oral health.
But excessive presence of certain types of bacteria causes tongue discoloration, i.e. purple tongue. More commonly a white coating over the tongue is seen as a result of bacterial presence on the tongue.
To get rid of the excessive bacteria and purple tongue, one should gently brush the tongue with the help of tongue scraper or toothbrush to get rid of the white coating of the bacteria and also prevent bacteria and dead cells from accumulating on the tongue. Seek medical attention if you are also having pain in the tongue along with the purplish discoloration.
