Nobody has watched ashwagandha's cortisol drop past 16 weeks
The trials ran 16 weeks at most and reported no serious side effects. Past that nothing has been measured, and the review that gathered them asks for medical supervision past the short term.
What the study found
What the cortisol drop does to the glands making it was never measured
The trials where cortisol fell against placebo ran 112 days at the outside. What lowered cortisol does to the adrenal glands, which produce the hormone, has never been measured. The review that gathered those trials asks for medical supervision past the short term.
The caveat · A gap, not a recorded harm
This is a gap in what has been measured, not a recorded harm: no trial reported an adrenal problem, because none of them looked for one. Inside their 30-to-112-day windows the trials reported no serious side effects.
