Eucalyptus trees are among the tallest trees and offer many medicinal benefits. Eucalyptus oil, which has a pale yellow color and distinctive aroma, comes from extracting the leaves. It requires dilution before medicinal use. According to Ayurveda, applying eucalyptus oil topically with a carrier oil like coconut oil can help manage acne due to its antibacterial properties, which inhibit acne-causing bacteria. Adding 2-3 drops of eucalyptus oil to a warm bath may also fight certain skin infections. Massaging eucalyptus oil on the chest and back provides relief from cold, cough, and nasal congestion by promoting sputum secretion to clear the airways and treat respiratory infections through expectorant and anti-inflammatory properties that reduce airway inflammation and ease breathing. Applying eucalyptus oil to your beard may also improve hair growth.
