Carboxymethyl cellulose (CMC), also known as cellulose gum, is a medical substance commonly used as a lubricant and thickener in various medical applications. 

Here's a breakdown of its key applications in the medical field:

• Artificial tears: CMC is a common ingredient in artificial tears solutions, which help lubricate and moisturize the eyes for people suffering from dry eye syndrome.
• Laxative: In some cases, CMC is used as a bulk-forming laxative to promote bowel movements by absorbing water and adding bulk to stool.
• Disintegrant: In the pharmaceutical industry, CMC is used as a disintegrant in tablets and capsules. This helps them break apart more easily in the digestive system, allowing for faster absorption of the medication.

It's important to note that CMC is generally considered safe for most people when used as directed. However, it can cause some mild side effects like:

• Mild stomach cramps
• Bloating
• Gas

If you experience any of these side effects, consult with your doctor.
