Sucking blood

Actually it's said that saliva has healing properties. Most animals like cows, monkeys,dogs etc heal their wound by licking it. It might be gross for some. But I always do that

I thought it was to get rid of the blood so you can see the wound and see how serious it is. Also I would of thought the plaster would stick better on a dry wound. Though it is probably better to use tissue or something to clean the wound.

I don't do that. It's kinda gross to me. Also not very hygienic.

People instinctively suck a finger wound because it can clean out any harmful substances from the wound that whatever caused the cut introduced. Whether that be a splinter, a bit of gravel or even some germs. Normally a person will spit out foreign matter from a wound and even if they swallow the foreign germs, our stomach acid will destroy those.

I have done it myself and don’t know why.

I'd rather lick off the blood than get blood on my clothes or hanky. Mum would always spit on an itch.

Yes, it does.

I don't know why people do this but I've done it myself. Seems weird doesn't it

i automatically do that when my finger gets cut. i once heard someone said so the blood can get into our body again after it gets out from being cut. i know it's not the real reason, that person is just messing around i think haha
