A total of 19 elements including essential and non-essential elements were characterized in five commercial samples of &lt;em&gt;Triphala churna&lt;/em&gt; using WD-XRF spectrometry. &lt;strong&gt;Method:&lt;/strong&gt; The WD-XRF method was validated for each element by a pre-calibrated program using five Chinese certified reference materials of vegetable standards (NCS ZC73012, NCS ZC73013, NCS ZC73017, NCS ZC85006 and NCS DC73348). &lt;strong&gt;Results:&lt;/strong&gt; The following elements were detected in all the samples out of 19 elements tested with increasing order of concentrations (mg/kg): Cr (3) &amp;lt; Cu (7) &amp;lt; Ba (24) &amp;lt; Zn (31) &amp;lt; Pb (46) &amp;lt; Mn (57) &amp;lt; S (700) &amp;lt; Na (1064) &amp;lt; Mg (1250) &amp;lt; Fe (1329) &amp;lt; P (1400) &amp;lt; Cl (2960) &amp;lt; Ca (3110) &amp;lt; Si (4350) &amp;lt; K (15130). Lead (41-46 mg/kg), a nonessential element was found above its PDE limit (&amp;le; 10 mg/kg). &lt;strong&gt;Conclusion:&lt;/strong&gt; WD-XRF method was found simple, rapid, reliable and non-destructive technique to investigate the elemental concentrations in herbal drugs.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">378</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Venkata Siva Satyanarayana Kantamreddi&lt;sup&gt;1*&lt;/sup&gt;, V.
