Kava is made up of kavalactones; psychoactive compounds that act as central nervous system depressants. The rare occurrence of kavalactone toxicity manifests most commonly with hepatotoxicity, and cases of myoglobinuria have been reported. Our case describes an association of significant kava tea ingestion with acute tubulo\u2010interstitial nephritis. An 18\u2010year\u2010old male, without any medical comorbidities, presented with oliguric acute kidney injury after ingesting 15 cups of kava tea. His creatinine at admission was 223umolL and peaked at 96\u2009h post ingestion at 970umol\/L despite intravenous fluid administration. His urine ACR was 196\u2009mg\/mmol, with microscopic haematuria; a creatinine kinase was 780\u2009U\/L, C3 was mildly reduced (0.77\u2009g\/L) with normal C4, and the remainder of a glomerulonephritis screen was negative. He did not have any evidence of hepatotoxicity but was bradycardic with a prolonged QT interval. A urine drug screen was negative for other substances. A kidney biopsy demonstrated severe acute tubulointerstitial nephritis without acute tubular necrosis or evidence of myoglobulin\u2010related injury. He was commenced on oral corticosteroids and had complete recovery of his kidney function after 2\u2009weeks, without requiring kidney replacement therapy. Toxicology analysis of the kava powder identified four different kavalactones without additional substances.<\/jats:p>","DOI":"10.1111\/nep.70051","type":"journal-article","created":{"date-parts":[[2025,5,8]],"date-time":"2025-05-08T06:58:57Z","timestamp":1746687537000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Case Report: Something Is Brewing"],"prefix":"10.1111","volume":"30","author":[{"given":"Kate","family":"Brotherton","sequence":"first","affiliation":[{"name":"Nephrology and Transplantation Unit John Hunter Hospital  Newcastle New South Wales Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0292-5512","authenticated-orcid":false,"given":"Bobby","family":"Chacko","sequence":"additional","affiliation":[{"name":"Nephrology and Transplantation Unit John Hunter Hospital  Newcastle New South Wales Australia"},{"name":"School of Medicine and Public Health University of Newcastle  New South Wales Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,5,7]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/10590500801907407"},{"key":"e_1_2_8_3_1","unstructured":"Kava in the NDSHS \u201cAustralian Institute of Health and Welfare \u201d2024 https:\/\/www.aihw.gov.au\/reports\/illicit\u2010use\u2010of\u2010drugs\/kava\u2010ndshs."},{"key":"e_1_2_8_4_1","unstructured":"Kava Clinical Factsheet \u201cNSW Health \u201dhttps:\/\/www.health.nsw.gov.au\/aod\/resources\/Pages\/kava\u2010clinical\u2010factsheet.aspx."},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.5694\/j.1326\u20105377.1988.tb93809.x"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm11144039"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.5694\/j.1326\u20105377.2003.tb05289.x"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajem.2011.01.030"},{"volume-title":"Allergic and Drug\u2010Induced Interstitial Nephritis","year":"2023","author":"Finnigan N.
