Garlic oil is an essential oil extracted from the bulbs of the garlic plant. It has a strong, pungent, and spicy aroma. It is known for its antimicrobial and antiviral properties and has been traditionally used to help with colds, flu, and other respiratory infections. Garlic oil is also believed to have anti-inflammatory properties, which may make it useful for treating certain skin conditions. Some people also use it as a natural remedy for hypertension, high cholesterol, and other cardiovascular issues. Garlic oil is typically used in aromatherapy, massage, and as a flavoring agent in food and beverages. It is considered safe for most people when used topically and in small amounts when used internally. However, it's always best to consult with a healthcare professional before using it internally, especially if you're on blood-thinning medications or have a bleeding disorder.
