How long before scheduled surgery must lavender preparations, including tea, be discontinued?
Answer
Two weeks
There is a significant cautionary advisory regarding the use of lavender preparations before surgical procedures due to its known ability to affect blood clotting mechanisms. Healthcare professionals strongly recommend discontinuing the use of lavender in any form, including routine consumption of lavender tea, for a minimum duration of two weeks leading up to any scheduled surgery. This strict timeframe is necessary because lavender possesses properties that may slow blood clotting. Failing to cease consumption within this window increases the potential risk of experiencing excessive or problematic bleeding either during the operation itself or during the recovery period following the invasive medical procedure.
