I'm terribly sorry that your mother didn't hug you enough when you were a baby (or whatever your problem is) but, if you don't mind, some of us would like to engage in at least semi-intelligent conversation here.
Pap, you were asking about plants. Another use for plants could be a herbal rinse for the hair. For oily hair, a rinse of 1 teaspoon of burdock root, chamomile, calendula lavender flowers, lemongrass add sage leaves in a large container then pour 1 pint of boiling water over and steep for 30 minutes, strain and add 1 tablespoon of vinegar and if you are able to shampoo pour this mixture over your scalp and leave without rinsing. In a survival situation in the woods this would not be first priority but personal hygiene is a second issue too.
