This name comes from the Latin <em>lavare<\/em>, which means \u201cto wash\u201d, due to its use as an antiseptic and disinfectant since antiquity among the ancient Arabs, Greeks and Romans (DENNER, 2009). Among the different species, we find lavender officinalis (also called true lavender, <em>Lavandula angustifolia<\/em>, <em>Lavandula officinalis<\/em>, or <em>Lavandula vera<\/em>).<\/p>\n<p>Aspic lavender &#8211; LAVANDULA LATIFOLIA<br \/>\nAspic lavender or <em>Lavandula latifolia<\/em> is another species of lavender. Its name is inspired by that of the asp viper whose bite it is reputed to treat. Indeed, Aspic lavender essential oil has been known for many years for its soothing, regenerating and healing properties (SHIMIZU &#038; al., 1990&#8239;; CAVANAGH &#038; WILKINSON, 2002). It is a plant that grows at a lower altitude of 600 meters, while lavender officinalis grows from 800 meters and up to 2,000 meters of altitude. Its flowering occurs later than lavender officinalis (GARZOLI &#038; al., 2019). <\/p>\n<p>As for lavandin, it is a natural hybrid born from the reproduction between lavender officinalis and aspic lavender (LESAGE-MEESSEN &#038; al., 2015). Lavandin is found between 200 and 800-1,000 meters above sea level (GARZOLI &#038; al., 2019). Information about lavandin can be found in the specific technical sheet for this active ingredient. <a href=\"https:\/\/miloa.eu\/en\/glossary\/plants\/lavandin\/\" rel=\"noopener noreferrer\" target=\"_blank\"> Here<\/a> <\/p>\n","protected":false},"author":3,"featured_media":17338,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_relevanssi_hide_post":"","_relevanssi_pin_for_all":"","_relevanssi_pin_keywords":"","_relevanssi_unpin_keywords":"","_relevanssi_related_keywords":"","_relevanssi_related_include_ids":"","_relevanssi_related_exclude_ids":"","_relevanssi_related_no_append":"","_relevanssi_related_not_related":"","_relevanssi_related_posts":"","_relevanssi_noindex_reason":"","footnotes":""},"categories":[182],"tags":[402,659,277,216],"class_list":["post-17346","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-plants","tag-product-der-miloa-en","tag-flex-miloa-en","tag-index-plantes-en-l","tag-product-zen-miloa-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/posts\/17346","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/comments?post=17346"}],"version-history":[{"count":0,"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/posts\/17346\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/media\/17338"}],"wp:attachment":[{"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/media?parent=17346"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/categories?post=17346"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/tags?post=17346"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
