Essential oil was isolated by hydro-distillation, analysed using GC-MS, UV-Visible Spectrophotometer and other established biochemical assays were used for the study. The GC-MS analysis of the aerial essential oil of&lt;em&gt; L. crispata&lt;/em&gt; showed the presence of 35 medicinal organic compounds making up 84.4% of the oil. The most abundant component was a phenolic compound called 2-tert-Butyl&lt;sup&gt;-1&lt;/sup&gt;,4-dimethoxybenzene (54.5%). The other major terpenoids present in the oil were α-humulene (6.9%) and (+)-sabinene (5.9%). The TPC, TFC, TAA and TAC values of the aerial essential oil of &lt;em&gt;L. crispata &lt;/em&gt;were 172.75±0.00 μgmg&lt;sup&gt;-1&lt;/sup&gt; GAE, 48.69±0.00 μgmg&lt;sup&gt;-1&lt;/sup&gt; QE, 61.85±0.00 μgmg&lt;sup&gt;-1&lt;/sup&gt; AAE and 726.92±0.00 μgmg&lt;sup&gt;-1&lt;/sup&gt; AAE respectively. DPPH IC&lt;sub&gt;50 &lt;/sub&gt;and AAI values of the essential oil were 1.5 μgml&lt;sup&gt;-1&lt;/sup&gt; and 26.7. The essential oil displayed varying inhibitory activities against Gram-positive and Gram-negative bacteria with zones of inhibition ranging from 08-30 mm. The&lt;em&gt; in vitro&lt;/em&gt; pharmacological activities added scientific support to the use of &lt;em&gt;L. crispata&lt;/em&gt; in alternative and complementary medicine. The essential oil of &lt;em&gt;L. crispata&lt;/em&gt; grown in Nigeria will play beneficial roles in human and animal health and therefore a research on this plant might be of great value in drug industries.&lt;/p&gt;
