Yes, that sounds like it, it is usually mucus with old blood mixed in, hence the color.
Because it contains undigested food, mucus, dead body tissue and toxins
they get their by well it depends on what is in the mucus. or if you are in a dirty location your boogers will come out brown or dirty.
The poisonous gland is larger than the mucus gland and provides protection and defenses for the body. The mucous gland is smaller than the poisonous gland and its function is to provide moisture for the skin.
I will suggest you talk with your physician about this. Most commercial poison ivy medications are not intended for use on the mucus membranes (which the genitalia are), so you may need a prescription medication for the itch/rash.
That is normal congestion if you have a cold or bad allergies. Dried up mucus is usually white or yellowish or brownish. If you get bright yellow or greenish, you probably have an infection, but dark colors are just dried out mucus.
Its made up of undigested foods, mucus and dead body cells as well as toxins
no theyre not, unless they have sharp teeth :)
