Trees in the U.K. are being [injected](http://www.bbc.com/news/science-environment-29522647) with a garlic extract to cure them of deadly diseases, the BBC reports. “Over the last four years we have treated 60 trees suffering badly with bleeding canker of horse chestnut. All of the trees were cured,” said Jonathan Cocking, an arboreal specialist involved with the development and deployment of the treatment. “This result has been broadly backed up by 350 trees we have treated all over the country, where we have had a 95% success rate,” Cocking told the BBC. Garlic contains a compound called allicin, which has antibacterial properties and can fight fungal infections too. The injection device, which is being deployed in forests in the English Midlands, is made up of a pressurized chamber with eight tubes that inject the allicin solution directly into a tree’s sap system. The needles are positioned to ensure the even spread of allicin all around the tree. According to the BBC, scaling up this method of treatment is costly and impractical. However, it can be used to save trees of historic or sentimental value. \[[_BBC_](http://www.bbc.com/news/science-environment-29522647)\] Garlic Being Used in the U.K. to Cure Trees of Deadly Diseases ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3480014/garlic-injection-trees-disease/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3480014/garlic-injection-trees-disease/"},"headline":"Garlic Is Being Used in the U.K. to Cure Trees of Deadly Diseases","datePublished":"2014-10-08T05:05:22.000Z","dateModified":"2026-02-21T10:38:55.055Z","description":"The bulbs contain the compound allicin, which can fight bacterial and fungal infections","url":"https://time.com/3480014/garlic-injection-trees-disease/","keywords":["Environment","uk","trees"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt0034d138a29581f7/69875f3acd68487f10096eaf/456793292.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Rishi Iyengar","jobTitle":null,"url":"https://time.com/author/rishi-iyengar/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt0034d138a29581f7/69875f3acd68487f10096eaf/456793292.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Autumn Colours Begin To Show In The UK","caption":"Autumn Colours Begin To Show In The UK","creditText":"Matt Cardy—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/environment/","name":"Environment"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3480014/garlic-injection-trees-disease/","name":"Garlic Is Being Used in the U.K. to Cure Trees of Deadly Diseases"}}]}] ```
