Old tea bags may not be good for tea, but do have other uses. Several can be added to bath water to help ease sunburns, poison ivy itches and such. A wet bag can also be used to ease razor burn. You can cover a boil or “zit” to help bring it to a head. Supposedly a wart can be treated by covering it with a wet tea bag for 10-15 minutes several times a day. Moist tea bags can be cooled in the refrigerator and used as compresses for puffy eyes and even for headaches.
It can even be used to treat hair. Brew 2 tea bags in a quart of water, cool and pour over your hair as a conditioner. Rinse well or just pat it dry if you want red highlights. This same concoction can be used to clean wood floors and furniture and as a dye for fabric.
The bag can be opened and the dry leaves sprinkled on the carpet and then vacuumed to leave a nice scent. Dry herbal tea bags can be placed in shoes and drawers as sachets.
Tea can be used as fertilizers and gardenias and ferns are supposed to love them. And, finally, used tea bags can be placed in the compost heap to speed decomposition of the rest of the heap.
There are even more uses for the tea. I personally have not tried a lot of these remedies, so cannot really recommend them. Use at your own risk.
