Eucalyptus leaves have many uses, including:

1. Tea: Eucalyptus leaves can be brewed into tea, which is safe for consumption. The tea contains flavonoids and tannins that have antioxidant properties and can help relieve cold symptoms, reduce pain, and promote relaxation.

2. Air freshener: Fresh eucalyptus leaves can be used as an air freshener. A few fresh springs in a vase placed in any room creates a wonderful aroma of eucalyptus that will last anywhere between 1-2 weeks. Once the leaves have dried, they can be used to make other suggestions.

3. Decoration: Dried eucalyptus holds its shape very well and can be used for decoration in vases or turned into DIY wreaths or wall hangings during the holidays. Dried eucalyptus leaves can also be used in potpourri or dried floral arrangements.

4. Therapeutic benefits: Eucalyptus leaves have many therapeutic benefits, from reducing discomfort to freshening breath. Eucalyptus oil can be used topically or for inhalation, but should not be consumed. Eucalyptus plants contain components with antibacterial, antiseptic, and expectorant properties. One of these components is called cineole, which loosens phlegm, eases coughs, and aids other common respiratory issues. Eucalyptus oil can also be used as a massage oil to treat skin inflammation and arthritis.

5. Tincture: Fresh eucalyptus leaves can be turned into a tincture by putting a half pound or so of fresh leaves into a large jar and covering it with vodka. Seal the jar and leave it for a couple of weeks, shaking it every so often. After two weeks, strain the contents through muslin. The tincture can be used as a natural bug spray or as a massage oil.

6. Decongestant steam: Eucalyptus leaves can be used to make a decongestant steam. Boil a pot of water and add a handful of fresh eucalyptus leaves. Remove from heat and place your face over the pot, covering your head with a towel. Inhale the steam for 5-10 minutes.

7. Linen sachets: Dried eucalyptus leaves can be turned into linen sachets to keep your clothes smelling nice. Place the dried leaves in a little bag and hang in your wardrobe or drawers. You can add other ingredients like dried orange peel, lavender, or flowers.

When using eucalyptus leaves, it is important to note that the essential oil should not be consumed, as it can be harmful even in small amounts.
