Ok, if I had to pick one soap as my favorite (and it would be a very close race with many ties) - it would definitely be this one. While I love the variety of fragrance oils - my heart still lies with the all natural essential oils. And this scent is hard to beat. I use six different essential oils - each one for a specific purpose; and they all come together for a harmonious blend of perfection. And... I love the design. It's so bright and cheerful! 
Bonus - the beautiful green color comes from Chlorella, so your skin is getting all the benefits of this algae as well! Chlorella is one of the most nutrient-dense superfoods that helps to boost collagen production. And... I love the design. It's so bright and cheerful!
 
Heavenly blend of 6 different essential oils:
 
Eucalyptus Oil: Eucalyptus oil eases congestion and aids breathing by helping the body to expel mucus.
Lavender Oil: Helps to relax the muscles of the lungs and airways allowing them to function better.
Lemon Oil: Antiseptic and antimicrobial, stimulates lymphatic drainage and helps the body cleanse itself of wastes and toxins.
Peppermint Oil: The menthol in peppermint makes it a great decongestant, reducing inflammation and causing swollen nose membranes to shrink.
Rosemary Oil: works as an expectorant, meaning that it can relieve throat congestion from the flu, colds, and allergies. Its antioxidant qualities can boost the immune system as well.
Tea Tree: Inhibits the growth of potentially harmful bacteria, helping to ease coughing and prevent further bronchial damage.
