Basil Essential Oil: Benefits, Uses, DIY Recipes & Diffuser Blends

Fresh, green, slightly sweet, and unmistakably herbal, Basil Essential Oil (Ocimum basilicum) brings the familiar aroma of the herb garden into an incredibly concentrated essential oil.

While most of us first think of basil in the kitchen, Basil Essential Oil offers an entirely different way to experience this aromatic plant.

Its refreshing herbal aroma makes it a wonderful oil for diffusing, massage blends, personal care, natural home fragrance, and DIY recipes. It also blends surprisingly well with citrus, floral, minty, woody, and other herbal essential oils.

Whether you're looking for something fresh to diffuse while working, a new addition to your massage routine, or simply another versatile oil to explore, there's a lot you can do with a bottle of Basil Essential Oil.

What Is Basil Essential Oil?

Basil (Ocimum basilicum) belongs to the mint family and has been cultivated around the world for generations.

Basil Essential Oil is produced by steam distilling the aromatic plant material. The resulting essential oil has a concentrated aroma that can be described as fresh, herbal, warm, green, and slightly spicy.

Basil Essential Oil DIY Recipes

Now let's put your Basil Essential Oil to work.

DIY #1: Garden Fresh Room Spray

Bring the aroma of a fresh herb garden indoors.

You'll Need:

• 10 drops Basil 
• 10 drops Lemon 
• 5 drops Lavender 
• 1 tablespoon witch hazel
• Distilled water
• 4 oz glass spray bottle

Directions:

Add the essential oils and witch hazel to your spray bottle. Fill the remainder with distilled water and replace the sprayer. Shake thoroughly before each use and lightly mist into the air. Avoid spraying directly onto people, pets, finished surfaces, or delicate fabrics. Because essential oils do not remain evenly dispersed in water on their own, shake well before every use.

DIY #2: Garden Massage Oil

After a long day, try this simple aromatic massage blend.

You'll Need:

• 4 drops Basil 
• 3 drops Lavender 
• 2 drops Frankincense 
• 1 oz carrier oil

Directions:

Combine the ingredients in a glass bottle and shake gently. Apply a small amount during massage to the desired area. Avoid the face, eyes, and other sensitive areas. Always patch test before broader topical use.

DIY #3: Basil & Lemon Shower Steamers

Turn your shower into an aromatic herb garden.

You'll Need:

• 1 cup baking soda
• ½ cup citric acid
• 15 drops Basil 
• 15 drops Lemon 
• Witch hazel in a fine-mist bottle
• Silicone mold

Directions:

Combine the baking soda and citric acid. Add the Basil and Lemon Essential Oils and mix thoroughly. Lightly mist the mixture with witch hazel while stirring until it just holds together when squeezed. Don't oversaturate it. Press firmly into silicone molds and allow the steamers to dry completely. Place one shower steamer on the shower floor away from the direct stream of water and allow the steam to carry the aroma. These are intended for shower aromatics—not for use as bath bombs or for direct application to the skin.

DIY #4: Himalayan Salt Herb Diffuser

No diffuser? This simple Himalayan salt diffuser is an easy way to enjoy Basil's fresh herbal aroma in smaller spaces.

You'll Need:

• ½ cup coarse Himalayan pink salt
• 8 drops Basil 
• 8 drops Lemon 
• 4 drops Rosemary 
• Small glass jar or decorative bowl

Directions:

Add the Himalayan salt to your jar or bowl. Add the essential oils directly to the salt and stir gently to distribute the oils. Place it in a bathroom, office, mudroom, or other small space where you'd like a fresh herbal aroma. Give the salt an occasional stir to refresh the scent. When the aroma begins to fade, simply add a few more drops of essential oil. Keep out of reach of children and pets, and avoid placing the salt directly on surfaces that could be damaged by essential oils.

Tip: For a softer aroma, start with half the essential oils and add more until you reach the strength you prefer.

DIY #5: Herbal Hair & Scalp Massage Oil

Give your scalp a little extra attention before shampooing with this simple herbal oil. A pre-shampoo oil can help condition the hair and scalp, reduce the drying effects of shampoo, provide lubrication during scalp massage, and turn an ordinary wash day into a relaxing self-care routine.

Basil and Rosemary create a fresh, herbaceous aroma, while the carrier oil provides slip and conditioning during scalp massage. Rosemary is also particularly interesting for hair-care routines because it has been studied for its potential role in supporting hair growth.

You'll Need:

• 3 drops Basil 
• 3 drops Rosemary 
• 1 oz carrier oil

Directions:

Combine the ingredients in a glass bottle.

Apply a small amount to the scalp and gently massage with your fingertips. Allow the oil to remain on the scalp for 15–30 minutes, then shampoo thoroughly.

Use 1–2 times per week as part of your regular hair-care routine.

Always patch test before use and avoid contact with the eyes.
