In health, the body of the tongue is light pink to medium red in colour, with minimal cracks or fissures.

Deviations of normal include:
Thick white coating or patches- which can indicate candida, or thrush yeast infection.
Overly smooth tongue- which may indicate a variety of nutritional deficiencies including iron, b 12 and folic acid, especially if accompanied by soft gums that bleed easily.

Red or very red tongue- can be due to severe dryness, dehydration, xerostomia, Sjogren’s syndrome, or can be a symptom of menopause in women, or from use of prescription medications, or occur following chemotherapy or radiation therapy.
Enlarged tongue- is often found in people who are obese or over weight, as well as in people with various types of mental health conditions.

Eastern Medicine/ Traditional Chinese Medicine (TCM)
The tongue is a vitally important diagnostic tool especially relating to the health of the internal body systems. 

A TCM Practitioner will assess that tongue based on:
Colour of the body
Size: Length and Width, and thickness of body
Coating: Thickness, colour, greasy, oily, or dryness.
The tongue is divided according to locations of organs and in terms of 
Lower body (kidney, bladder), middle body (stomach/spleen), and upper body (Lung, Heart)
Pay Attention to Changes in Your Tongue!! This may indicate changes occurring inside the body.
