Holy basil might be the most underrated adaptogen for cortisol. Here’s what the research actually shows. 🧵 I’ve been drinking tulsi (holy basil) for years. I drank it almost every day during my years working as a clinical dietitian. I write about cortisol for a living, and this herb still earns a spot in my cupboard. I just updated my holy basil guide with the newest research. The key findings: 🧠 Stress: In an 8-week randomized, placebo-controlled trial, 100 stressed adults took 250 mg a day of a standardized holy basil extract. Their perceived stress dropped more than with placebo. 📉 Cortisol: Hair cortisol was markedly lower at week 8, and salivary cortisol spiked less during a lab stress test. 🌙 Sleep: Insomnia scores improved too. Fair caveat: the Fitbit data didn’t confirm it, so the benefit so far is based on how people felt. 🩸 Blood sugar: Small human trials show lower fasting and after-meal glucose. What I like most: holy basil tends to feel clarifying rather than sedating. It’s my pick for daytime stress, when I need to focus rather than wind down. ⚠️ Who should skip it: • Anyone pregnant, breastfeeding, or trying to conceive (animal studies show anti-fertility effects) • Anyone on blood thinners, diabetes meds, or thyroid meds without their provider’s OK And my usual reminder: test, not guess. If your cortisol already runs low in the afternoon, a cortisol-lowering herb isn’t automatically the answer. In the full guide: dosing from the studies, tea vs. tincture vs. capsules, how to grow your own, and the tulsi brands I actually use. 👇 thehealthyrd.com/10-best-hol… #TheHealthyRD #holybasil #tulsi #cortisol #adaptogens
