Green snot is not necessarily the last stage of a cold but indicates your body is fighting off the infection. The green color comes from the enzymes in white blood cells that are active during the battle against infection. The color can change throughout the illness, not signaling the end but rather the ongoing immune response. It's essential to monitor symptoms and consult a healthcare provider if they worsen or persist.
