They are generally liquid and consist of highly complex and volatile chemical mixtures. This unique composition gives them a strong characteristic aroma, making them valuable not only in <strong>aromatherapy<\/strong>, but also in the <strong>food, cosmetic, and nutraceutical industries<\/strong>.<\/p>\r\n<p>In this article, we will explore <strong>what essential oils are used for, how to use them<\/strong>, <strong>their benefits and contraindications<\/strong>, and, most importantly, why they play such an interesting role in human health.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">What Are Essential Oils Used For<\/h2>\r\n\r\n\r\n\r\n<p>In nature, essential oils are <strong>secondary metabolites<\/strong> that allow plants to:<\/p>\r\n<ul>\r\n<li>defend against pathogens and parasites;<\/li>\r\n<li>attract pollinators and animals that aid seed dispersal;<\/li>\r\n<li>communicate between individuals of the same species and among the plant\u2019s organs;<\/li>\r\n<li>protect themselves from environmental stress, such as UV radiation;<\/li>\r\n<li>limit the growth of nearby plants through release into the soil or air.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>In humans, these functions translate into potential <strong>antimicrobial, antioxidant<\/strong>, and <strong>anti-inflammatory benefits<\/strong>, which are increasingly studied in the <strong>nutraceutical sector<\/strong>.<\/p>\r\n<h2 class=\"wp-block-heading\">How to Use Essential Oils<\/h2>\r\n\r\n\r\n\r\n<p>Essential oils can be used in various ways, but it is important to do so safely:<\/p>\r\n<ul>\r\n<li><strong>External use<\/strong>: Thanks to their pleasant aroma, essential oils are widely used in <strong>aromatherapy<\/strong> to promote relaxation and improve sleep quality. They can be diffused in the environment using vaporizers or applied to the skin for massages and rubs. In this case, it is essential to <strong>dilute them in a carrier oil or cream<\/strong>, as using them undiluted may cause irritation.<\/li>\r\n<li><strong>Internal use<\/strong>: Some essential oils can be used in <strong>nutraceutical formulations<\/strong>. When considering <strong>how to take essential oils<\/strong>, it is crucial to remember that they must <strong>always be included in appropriate formulations<\/strong> and <strong>never consumed pure<\/strong>. Highly concentrated, undiluted extracts can damage mucous membranes.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Benefits of Essential Oils for the Gut and Microbiota<\/h3>\r\n\r\n\r\n\r\n<p>Research has shown that certain essential oils can <strong>positively interact with the gut microbiota<\/strong>, helping to restore balance in <strong>dysbiosis<\/strong> and reduce local inflammation. These extracts offer a revolutionary approach, as their <strong>broad-spectrum natural antimicrobial activity<\/strong> acts through several mechanisms, such as:<\/p>\r\n<ul>\r\n<li>preventing the formation of essential structures;<\/li>\r\n<li>inhibiting biofilm formation;<\/li>\r\n<li>compromising the cell membrane.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<figure id=\"attachment_3191\" aria-describedby=\"caption-attachment-3191\" style=\"width: 1200px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3191 size-full\" src=\"https:\/\/www.tgd.care\/wp-content\/uploads\/2025\/10\/infografica-essential-oils-1025.png\" alt=\"infografica essential oils 1025\" width=\"1200\" height=\"800\" srcset=\"https:\/\/www.tgd.care\/wp-content\/uploads\/2025\/10\/infografica-essential-oils-1025.png 1200w, https:\/\/www.tgd.care\/wp-content\/uploads\/2025\/10\/infografica-essential-oils-1025-300x200.png 300w, https:\/\/www.tgd.care\/wp-content\/uploads\/2025\/10\/infografica-essential-oils-1025-1024x683.png 1024w, https:\/\/www.tgd.care\/wp-content\/uploads\/2025\/10\/infografica-essential-oils-1025-600x400.png 600w, https:\/\/www.tgd.care\/wp-content\/uploads\/2025\/10\/infografica-essential-oils-1025-900x600.png 900w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption id=\"caption-attachment-3191\" class=\"wp-caption-text\"><em>Some components of essential oils can cross cell membranes. <strong>Gram-negative bacteria<\/strong> and <strong>fungi<\/strong> are particularly sensitive due to the lipophilic nature of their membranes and outer walls.
