Eupatorin, sinensetin and ursolic acid are the main agents responsible for these anti-inflammatory effects.<\/p>\n<ul style=\"color: #d61163;\">\n<li>\n<h3><font color=\"#d61163\">Beneficial effects on kidney function:<\/font><\/h3>\n<\/li>\n<\/ul>\n<p><em>O. stamineus<\/em> has many beneficial effects on kidney function. For example, it reduces uraemia and creatininaemia, and increases glomerular filtration rate <span class=\"prod_ref\">(ADAM &#038; al, 2009)<\/span>.<\/p>\n<p>It has a diuretic effect on rats comparable to that obtained with furosemide <span class=\"prod_ref\">(ENGLERT &#038; al, 1992&#8239;; SCHUT &#038; al, 1993)<\/span> and exhibits a dose-dependent diuretic activity <span class=\"prod_ref\">(ADAM &#038; al, 2009)<\/span>. Sodium and potassium excretion increases in the first eight hours of treating rats with a single dose of 2 g\/kg of <em>O. stamineus<\/em> in a pattern similar to that of hydrochlorothiazide. Repeated doses of 0.5 mg\/kg administered over a period of seven days cause an increase in urine volume from day 3 to day 7 and in electrolyte excretion (Na<sup>+<\/sup> and K<sup>+<\/sup> ions) from day 2 to day 7. Generally, reduced uric acid levels in serum are observed after six hours of treatment <span class=\"prod_ref\">(ARAFAT &#038; al, 2008)<\/span>.<\/p>\n<p><em>O. stamineus<\/em> also has renoprotective effects. For example, in rats given potassium oxonate, <em>O. stamineus<\/em> counteracts hyperuricaemia and reduces renal tissue damage <span class=\"prod_ref\">(WH &#038; al, 2020)<\/span>. To ensure these protective effects, ethanolic extract is more effective than aqueous extract, as it has a much higher content of caffeic acid, chlorogenic acid, protocatechuic acid and orthosiphol <span class=\"prod_ref\">(SACHAR &#038; al, 2018)<\/span>.<\/p>\n<ul style=\"color: #d61163;\">\n<li>\n<h3><font color=\"#d61163\">Antihypertensive effect: <\/font><\/h3>\n<\/li>\n<\/ul>\n<p>As a vasorelaxant, <em>O. stamineus<\/em> also has antihypertensive properties. It involves the calcium and potassium channels, but also the muscarinic and beta-adrenergic receptors. This has been observed in rats fitted with an aortic ring to induce hypertension. This effect is modulated by sinensetin <span class=\"prod_ref\">(YAM &#038; al, 2018)<\/span>.<\/p>\n<p>Another molecule derived from sinensetin, tetramethoxyflavone (TMF), causes vasorelaxation in the aortic arch of rats whose endothelium has been sensitised to phenylephrine. This effect is also obtained by acting on the calcium and potassium channels, and on the muscarinic and beta-adrenergic receptors <span class=\"prod_ref\">(TAM &#038; al, 2018)<\/span>.<\/p>\n<ul style=\"color: #d61163;\">\n<li>\n<h3><font color=\"#d61163\">Hepatoprotective effect:<\/font><\/h3>\n<\/li>\n<\/ul>\n<p>Due to its antioxidant abilities, <em>O. stamineus<\/em> has a hepatoprotective effect, counterbalancing the increased serum levels of the liver enzymes ALT and AST. It also protects against the harmful effects of paracetamol on the liver by raising glutathione levels <span class=\"prod_ref\">(ASHRAF &#038; al, 2018)<\/span>.<\/p>\n<ul style=\"color: #d61163;\">\n<li>\n<h3><font color=\"#d61163\">Anti-infectious activity:<\/font><\/h3>\n<\/li>\n<\/ul>\n<p>The antimicrobial activity of <em>O. stamineus<\/em> extract has been demonstrated in several studies.

A dose of 750 mg\/kg protects the kidneys and bladder against <em>E. coli<\/em> infection in mice, reducing bacterial concentration in a similar way to norofloxacin. Interestingly, pre-treatment with <em>O. stamineus<\/em> for four to seven days reduces bacterial bladder colonisation due to its antiadhesive activity <span class=\"prod_ref\">(SASHAR &#038; al, 2017)<\/span>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ORTHOSIPHON STAMINEUS<br \/>\nPopularly known as Cat\u2019s Whiskers or Java Tea, <em>Orthosiphon stamineus<\/em> is a plant native to South-East Asia and belongs to the Lamiaceae family.<br \/>\nIts leaves have been used since ancient times in traditional Chinese medicine for their anti-inflammatory, antioxidant, hepatoprotective and antimicrobial effects. <em>O. stamineus<\/em> is widely used as a diuretic and to combat rheumatism, abdominal pain, kidney and bladder inflammation or infection (nephritis, cystitis), oedema, gout and hypertension.<\/p>\n","protected":false},"author":3,"featured_media":15482,"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":[267,228],"class_list":["post-5733","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-plants","tag-index-plantes-en-o","tag-product-reno-pro-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/posts\/5733","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=5733"}],"version-history":[{"count":0,"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/posts\/5733\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/media\/15482"}],"wp:attachment":[{"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/media?parent=5733"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/categories?post=5733"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/miloa.eu\/en\/wp-json\/wp\/v2\/tags?post=5733"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
