Marsh Blazing Star + Lorcaserin
Lorcaserin brand name: Belviq.
We found no known interaction between Marsh Blazing Star and Lorcaserin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Marsh Blazing Star and Lorcaserin
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Lorcaserin and Marsh Blazing Star in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Marsh Blazing Star at all — not against Lorcaserin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

From our pharmacist’s overview on the Lorcaserin page
“Lorcaserin (Belviq) curbs appetite by stimulating serotonin receptors, which is exactly why I would slow down before pairing it with supplements. Half the entries below also push serotonin higher, and stacking them can edge toward serotonin syndrome, a dangerous serotonin overload.”

About Marsh Blazing Star

Marsh blazing star (Liatris spicata) is a North American prairie plant whose root has a long history in folk medicine for urinary, menstrual, and digestive complaints. There is very little modern scientific evidence to confirm that it works or to define a safe dose, so it should be used cautiously and avoided in pregnancy and breastfeeding.
