The Difference Between Cold Sores and Canker Sores

These two ailments are commonly confused. Both canker sores and cold sores can be triggered by stress, facial trauma, hormonal changes and food or drug hypersensitivity. Both can appear on the inside or outside of the mouth area and can be very painful.

The big difference between the two is that a canker sore is not contagious while any skin-to-skin contact with an active cold sore blister can trigger an infection in another person.

That’s why you should avoid close contact if you have a cold sore, or for that matter, notice one on someone else. Do not share any food, drink, straw, cup, lip balm, or anything that goes on or near your mouth. And no kissing!

The good news is you can boost your immune system through your nutrition and lifestyle habits to inhibit both canker sores and herpes virus outbreak. If you want to decrease the chances of getting a canker or cold sore you should:

Relax and lower your stress and anxiety levels. Fatigue and emotional stress are commonly associated with the appearance and severity of an outbreak. Make sure you get plenty of rest and relaxation.

Watch what you eat: Once a canker sore starts, avoid spicy and acidic foods or drinks. With a cold sore keep in mind that the herpes virus thrives with the amino acid arginine, but not with lysine.

My nutritional recommendations:


  • Fresh Vegetables and Fruits except Brussels sprouts and corn, which are high arginine.
  • Yogurt
  • Eggs (poached or soft boiled, but not fried)
  • Fish* (baked, poached or broiled)

Minimize or omit:

  • Refined carbohydrates
  • Refined sugar
  • Fried foods and fatty meats
  • Cookies, cakes, ice cream
  • Chocolate
  • Nuts (almonds, cashews, peanuts)

These nutritional tips along with PURICA Immune 7 will have your pout ready to pucker up in no time!

Most canker sores heal without medication, usually within 7-14 days.

For most people the body has the cold sore causing virus back under control in 8-10 days from onset of symptoms without medication.
