Infections result in exotoxin production, tissue necrosis and unless promptly treated, often result in death. &lt;strong&gt;Methods:&lt;/strong&gt; &lt;em&gt;Tasmannia lanceolata&lt;/em&gt; extracts were investigated for &lt;em&gt;C. perfringens &lt;/em&gt;growth inhibitory activity by disc diffusion analysis and MIC determination. Toxicity was evaluated by Artemia nauplii bioassay and the most potent extracts were phytochemically evaluated by GC-MS headspace analysis. &lt;strong&gt;Results:&lt;/strong&gt; All &lt;em&gt;T. lanceolata&lt;/em&gt; berry and leaf extracts displayed potent&lt;em&gt; C. perfringens&lt;/em&gt; growth inhibition. The berry extracts were more potent growth inhibitors than the corresponding leaf extracts, although the leaf extracts were also potent growth inhibitors. The berry aqueous, methanolic and ethyl acetate extracts were particularly potent growth inhibitors, with MIC values of 654, 65 and 329 &amp;mu;g/mL respectively. &lt;em&gt;T. lanceolata &lt;/em&gt;leaf also displayed good efficacy, with an MIC of 839, 1255 and 625 &amp;mu;g/mL for the aqueous, methanolic and ethyl acetate extracts respectively. All extracts were nontoxic in the &lt;em&gt;Artemia franciscana&lt;/em&gt; bioassay, with LC&lt;sub&gt;50&lt;/sub&gt; values substantially &amp;gt; 1000 &amp;mu;g/mL. Non-biased GC-MS analysis of the aqueous, methanolic and ethyl acetate berry extracts revealed the presence of high relative levels of a diversity of terpenoids. &lt;strong&gt;Conclusions:&lt;/strong&gt; The lack of toxicity of the T. lanceolata extracts and their potent growth inhibitory bioactivity against &lt;em&gt;C. perfringens&lt;/em&gt; indicates their potential as medicinal agents in the treatment and prevention of clostridial myonecrosis and enteritis necroticans. GC-MS metabolomic profiling studies indicate that these extracts contained a diversity of terpenoids, with monoterpenoids being particularly abundant.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">626</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Mitchell Henry Wright,&lt;sup&gt;1,2&lt;/sup&gt; Cameron Jay Lee,&lt;sup&gt;2&lt;/sup&gt; Megan Sarah Jean Arnold,&lt;sup&gt;3&lt;/sup&gt; Joseph Shalom,&lt;sup&gt;2,4&lt;/sup&gt; Alan White,&lt;sup&gt;2&lt;/sup&gt; Anthony Carlson Greene,&lt;sup&gt;2&lt;/sup&gt; Ian Edwin Cock &lt;sup&gt;2,4 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
