Bruises
Tender black-and-blue marks from a bump that fade on their own — cooled early, then warmed, and helped by a vitamin-C-rich diet.
📝 Summary

First thing to try: Right away, hold a cold compress or covered ice pack on the spot for about 20–30 minutes to limit swelling and shrink the mark.
See a doctor if: Bruises that appear often with no clear cause
🌿 Overview
A bruise is trapped blood under unbroken skin after a knock. Cooling it right away limits the mark; gentle warmth the next day helps clear it. Most fade within two weeks. A diet rich in fresh fruits and vegetables keeps blood vessels strong and bruising down.
A bruise forms when a bump or knock breaks tiny blood vessels under the skin, so a little blood leaks into the surrounding tissue. The skin itself stays unbroken, but you see the trapped blood as a tender, black-and-blue mark that slowly changes color — purple, then green, then yellow — as the body cleans it up and reabsorbs the blood. Most bruises are harmless and fade on their own in about two weeks. The most useful thing you can do is act fast: cooling the spot right away keeps the swelling and the size of the mark down. After the first day, gentle warmth helps the body carry the old blood away. Some people bruise more easily than others. This can simply run in families, but it can also point to a diet low in fresh fruits and vegetables, since vitamin C helps keep blood vessels strong. Frequent, unexplained bruising is worth a doctor's look.
Common signs
- A tender spot that turns black-and-blue
- Color that shifts from purple to green to yellow as it heals
- Mild swelling at the spot
- Soreness when pressed

- Dark leafy greens for vitamin K, which helps clotting
- Whole, colorful plant foods rich in natural plant pigments (bioflavonoids)
- Plenty of water
Go easy on
- Highly processed, low-nutrient junk foods
- Excess alcohol, which weakens clotting

- Frequent bruising for no clear reason deserves a medical check.
