Title: Do you have digoxin-like toxins growing in your backyard?<br/>Author: Hong Kim<br/><a href='http://umem.org/profiles/faculty/526/'>[Click to email author]</a><hr/><p>
Many medications are discovered from plants (quinine – cinchona trees) or organisms (penicillin – mold [penicillicum]).</p>
<p>
Digoxin was isolated from foxglove (Digitalis lanata), a colorful floral plant often found in many gardens. There are other sources of cardioactive steroids (aka cardiac glycosides) that have similar effect as digoxin.</p>
<ul>
<li>
Oleander (Nerium oleander)</li>
<li>
Yellow orleaner (Thevetia peruviana) – frequently used for suicide in Southeast Asia</li>
<li>
Lily of the valley (Convallari majalis) – use in wedding bouquet</li>
<li>
Dogbane (Apocynum cannabinum)</li>
<li>
Red squill (Urginea maritima)</li>
<li>
Bufo toad (Bufo species) </li>
</ul>

<p>
Non-digoxin cardioactive steroid exposure can result in a positive digoxin level due to cross reactivity. This confirms exposure; however, the “digoxin level” does not represent the true extent of the ingested dose or toxicity. </p>
<p>
Non-digoxin cardioactive steroid toxicity</p>
<ul>
<li>
Digibind also binds to non-digoxin cardioactive steroids.</li>
<li>
However, larger doses are often required (initial dose: 10 to 20 vials) than doses required for digoxin toxicity. </li>
