Hydrolats are the aromatic waters produced by the steam distillation of botanical material, usually during the production of essential oils. Hydro means water and lat comes from the word for milk, because when fresh these waters can be cloudy or milky from the suspended soluble plant extracts. Hydrolats are gentle and effective. They contain only the most water-soluble chemicals from the plant material plus microscopic drops of the essential oils. They may be used undiluted without problems but it is usually unnecessary as they are just as effective in dilution – less can be more! Generally calming and soothing with very few contra-indications, hydrolats can be safely used with children, animals, in combination with homeopathic remedies and for those with a fragile immune system when stronger treatments may not be well tolerated. Hydrolats can be combined into blends and synergies based on their properties and their scent to create health – promoting essences. Hydrolats can last for up to two years if they are kept cool and dark (preferably refrigerated).
