There are several really good toxin-free uses for overripe bananas like…
7 Uses for Overripe Bananas
1. Banana Sugar Scrub
Banana’s nutrient-rich flesh is a great skin moisturizer and works perfectly as the base of a sugar scrub; and your skin won’t know the difference if the banana has seen better days. Lightly mash one banana with three tablespoons of granulated sugar, a teaspoon of olive oil, and a few drops of vanilla extract or the essential oil of your choice (optional). Get in the shower and before turning on the water, massage the mix all over. Rinse. Feel sweet and smooth.For a quick facial, reserve some of the plain banana (without sugar) and massage on your face, avoiding the eye area. Rinse.
2. Smoothie Ice
Nothing makes for a diluted-tasting, watery smoothie like ice as it melts. Nothing makes for a rich and creamy smoothie like frozen banana. So, trade ice cubes for frozen banana chunks; overripe bananas, once frozen, seem good as new when blended into oblivion. Peel bananas, slice, freeze. Use in place of ice. Done.
3. Butterfly Bait
Come to the rescue of hungry butterflies! You can use three overripe bananas in a formula that can help feed butterflies. See Make Food for Struggling Monarch Butterflies
4. Shoe Polish
An old trick of the Marines, ditch the toxic shoe polish and employ a banana peel to buff your leather shoes into shiny perfection. It really works. Peel the banana (and use the guts in any of the other uses listed here), rub the inside of the peel on shoes, then buff with a soft cloth.
5. Rose Bloom Happy-Maker
If the bloom on your rosebush has faded, try this—many a rose whisperer swear by it. Puree one overripe banana with a one-half cup of water in the blender. Lightly dig up the soil around the rose, pour the mix in, and blend into the soil. Next up: Stellar blooms!
6. Houseplant Booster
Enrich your houseplant water with this banana-based booster. Put a banana peel in a large jar and cover with water. Use this “juice” in your regular watering can: one part banana juice to five parts water. Water plants. You can keep adding water to the banana jar, too, to keep a fresh supply of the super-water coming.
