New research confirms that Lavender oil helps in labor pain.
A recently published study investigated the effect of Lavender inhalation on the severity of labor pain and duration of labor. The Lavender group inhaled diluted essential oil for three minutes at three different labor stages, and experienced a significant drop in pain levels. For example 9.6 to 7.6 at 9-10 cm dilation after the intervention. There was no effect on the duration of labor, suggesting that Lavender oildoes not affect labor progression.
This is consistent with the findings of a 2000 study by Ethel Burns et al, where 344 mother used Lavender oil during childbirth and 54% reported reduced pain levels, though these were not graded. No adverse effects were reported.
A 2014 study in Tehran used Orange flower hydrosol (control group used saline). In the control group, pain increased from 7.5 (minimal dilation) to 9.5 (8-10 cm dilation) while in the aromatherapy group the increase in pain rating was marginal – from 7.4 to 7.6.
