Den tr\u00e6nger ind gennem s\u00e5r i barken og vokser derefter inde i stammen i mange \u00e5r. Udenp\u00e5 ser man en sort, revnet udv\u00e6kst med et rustbrunt, korkagtigt indre.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1280\" height=\"1708\" src=\"https:\/\/rawhemp.eu\/wp-content\/uploads\/2026\/09\/chaga-birch.webp\" alt=\"Sort, revnet chaga p\u00e5 stammen af et birketr\u00e6\" class=\"wp-image-60929\" style=\"width:400px\" srcset=\"https:\/\/rawhemp.eu\/wp-content\/uploads\/2026\/09\/chaga-birch.webp 1280w, https:\/\/rawhemp.eu\/wp-content\/uploads\/2026\/09\/chaga-birch-225x300.webp 225w, https:\/\/rawhemp.eu\/wp-content\/uploads\/2026\/09\/chaga-birch-767x1024.webp 767w, https:\/\/rawhemp.eu\/wp-content\/uploads\/2026\/09\/chaga-birch-768x1025.webp 768w, https:\/\/rawhemp.eu\/wp-content\/uploads\/2026\/09\/chaga-birch-1151x1536.webp 1151w, https:\/\/rawhemp.eu\/wp-content\/uploads\/2026\/09\/chaga-birch-9x12.webp 9w, https:\/\/rawhemp.eu\/wp-content\/uploads\/2026\/09\/chaga-birch-920x1228.webp 920w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/><figcaption class=\"wp-element-caption\">Chaga p\u00e5 birk.

Det er et sklerotium, en steril masse af t\u00e6t sammenflettet mycelium, der er sort af store m\u00e6ngder melanin. Svampens egentlige frugtlegeme, det der spreder sporer, dannes f\u00f8rst, n\u00e5r tr\u00e6et eller en del af det er d\u00f8dt. Det vokser s\u00e5 skjult mellem barken og veddet og ses sj\u00e6ldent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Chaga vokser langsomt, og et angrebet tr\u00e6 kan leve i \u00e5rtier med svampen i stammen. Du kan l\u00e6se mere om forskellen mellem frugtlegeme og mycelium, og om hvordan svampeekstrakter laves, i vores <a href=\"\/da\/funktionelle-svampe-guide\/\">guide til funktionelle svampe<\/a>.<\/p>\n\n\n\n<h2 id=\"how-to-recognise-chaga\" class=\"wp-block-heading\">S\u00e5dan genkender du chaga<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Chaga er let at genkende, n\u00e5r man ved, hvad man skal kigge efter, men den forveksles nogle gange med andre ting p\u00e5 birkestammer:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Chaga.<\/strong> Uregelm\u00e6ssig, kulsort og dybt revnet p\u00e5 ydersiden. Indersiden er rustgul til brun og smuldrende eller korkagtig.<\/li>\n\n\n\n<li><strong>Knuder og masurv\u00e6kst.<\/strong> Udv\u00e6kster p\u00e5 stammen, der er d\u00e6kket af bark og best\u00e5r af h\u00e5rdt tr\u00e6 hele vejen igennem.<\/li>\n\n\n\n<li><strong>T\u00f8ndersvamp.<\/strong> En gr\u00e5, hovformet poresvamp med porer p\u00e5 undersiden. Det er et \u00e6gte frugtlegeme og ser helt anderledes ud.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"can-you-pick-chaga\" class=\"wp-block-heading\">M\u00e5 man plukke chaga?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ikke uden tilladelse. Chaga sidder godt fast i veddet og skal sk\u00e6res ud af tr\u00e6et, hvilket skader et levende tr\u00e6. I Sverige giver allemandsretten for eksempel lov til at plukke svampe i skoven, men den d\u00e6kker ikke chaga, s\u00e5 lodsejerens tilladelse er n\u00f8dvendig.<\/p>\n\n\n\n<h2 id=\"chaga-tea\" class=\"wp-block-heading\">Chaga te og chaga kaffe: en lang tradition<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Chaga har v\u00e6ret brugt i folkemedicin i Sibirien og Rusland siden mindst 1500-tallet. Khantyfolket i det vestlige Sibirien skar chaga i sm\u00e5 stykker og simrede den i vand til te. I Finland, hvor svampen hedder pakuri, beskriver en forskningsoversigt, hvordan soldater under Anden Verdenskrig brugte chaga som kaffeerstatning, da kaffen slap op.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Drikken bliver m\u00f8rk, n\u00e6sten som sort te, med en jordagtig og let bitter smag. Chaga indeholder ikke koffein, hvilket er en af grundene til, at den i dag s\u00e6lges som et alternativ til kaffe.<\/p>\n\n\n\n<h2 id=\"what-does-chaga-contain\" class=\"wp-block-heading\">Hvad indeholder chaga?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Forskere har fundet flere grupper af stoffer i chaga:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Melanin.<\/strong> Det m\u00f8rke pigment, der giver chaga dens sorte farve.<\/li>\n\n\n\n<li><strong>Triterpener.<\/strong> Blandt andet inotodiol og betulinsyre. Betulinsyren kommer delvis fra birken, som svampen vokser p\u00e5.<\/li>\n\n\n\n<li><strong>Polysakkarider.<\/strong> Blandt andet betaglukaner, den samme type stoffer, som findes i andre funktionelle svampe.<\/li>\n\n\n\n<li><strong>Polyfenoler.<\/strong> Plantestoffer, der ofte unders\u00f8ges i laboratoriet for deres antioxidante egenskaber.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">At betulinsyren kommer fra v\u00e6rtstr\u00e6et, er en af grundene til, at vild chaga fra birk adskiller sig fra chaga dyrket i laboratoriet.<\/p>\n\n\n\n<h2 id=\"research\" class=\"wp-block-heading\">Hvad siger forskningen om chaga?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Der findes mange studier om chaga, men n\u00e6sten alle er lavet p\u00e5 celler i reagensglas eller p\u00e5 dyr. Kontrollerede studier p\u00e5 mennesker mangler stort set. Flere nyere forskningsoversigter konstaterer, at der er brug for kliniske studier, f\u00f8r man kan sige noget om, hvordan chaga p\u00e5virker mennesker.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Det betyder ikke, at chaga er uinteressant, men det betyder, at mange p\u00e5stande om chaga p\u00e5 nettet g\u00e5r l\u00e6ngere, end forskningen viser.<\/p>\n\n\n\n<h2 id=\"oxalate\" class=\"wp-block-heading\">Oxalat: det vigtigste at vide om chaga<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Chaga indeholder meget h\u00f8je m\u00e6ngder oxalat, et stof der i store m\u00e6ngder kan danne krystaller i nyrerne. I 2014 beskrev japanske l\u00e6ger en 72-\u00e5rig kvinde, der i et halvt \u00e5r havde taget fire til fem teskefulde chagapulver om dagen og fik s\u00e5 alvorlige nyreskader, at hun m\u00e5tte i dialyse. I 2022 blev et lignende tilf\u00e6lde fra Sydkorea offentliggjort.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Det er f\u00e5 tilf\u00e6lde, men de viser, at mere ikke er bedre. Har du en nyresygdom, tager du medicin, er du gravid, eller har du en sygdom, er det klogt at tale med sundhedspersonale, f\u00f8r du bruger chaga.<\/p>\n\n\n\n<h2 id=\"wild-or-cultivated\" class=\"wp-block-heading\">Vild eller dyrket chaga?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Det meste af den chaga, der s\u00e6lges, er vildt h\u00f8stet fra birketr\u00e6er. Den stigende eftersp\u00f8rgsel har rejst sp\u00f8rgsm\u00e5l om, hvor meget der kan h\u00f8stes b\u00e6redygtigt. I Finland fors\u00f8ger forskere derfor at dyrke chaga ved at pode svampen ind i levende birketr\u00e6er.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Det viste sig at v\u00e6re lettere sagt end gjort. I et finsk fors\u00f8g blev 679 birketr\u00e6er podet. Fire til fem \u00e5r senere var gennemsnitligt 79 procent af tr\u00e6erne inficeret, men kun omkring 6 procent havde synlige udv\u00e6kster. Forskerne konkluderede, at chaga dannes langsomt, selv n\u00e5r podningen lykkes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vil du l\u00e6se om andre svampe, har vi ogs\u00e5 skrevet om <a href=\"\/da\/lions-mane-svamp\/\">Lion\u2019s Mane (pindsvinepigsvamp)<\/a>, <a href=\"\/da\/reishi-svamp\/\">reishi<\/a> og <a href=\"\/da\/cordyceps-svamp\/\">cordyceps<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vores chagaekstrakt og tinktur finder du under <a href=\"\/da\/kategori\/funktionelle-svampe\/\">funktionelle svampe<\/a> i vores shop.<\/p>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list\">\n<div id=\"faq-question-che1\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">Hvad er chaga?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>Chaga (Inonotus obliquus) er en svamp, der vokser p\u00e5 birk.
