No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Lathyrus and Rosuvastatin 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.

Lathyrus and Rosuvastatin

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 Rosuvastatin and Lathyrus 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 Lathyrus at all — not against Rosuvastatin, 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.

What to actually watch for

What Lathyrus Itself Has Been Linked To

This is not an interaction — nothing below involves Rosuvastatin. It is the side-effect record for Lathyrus on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Lathyrus, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on Additional detail

    “Orally, consuming a diet high in lathyrus can cause neurotoxic manifestations including muscular rigidity, spasticity, weakness, paralysis, weak pulse, shallow breathing, convulsions, or death (6,58002,58008,58009,58012,58014,58018,58021,58023,58024). Consumption of lathyrus can also result in problems with collagen crosslinking.”

Everything above comes from the Natural Medicines adverse-effect record for Lathyrus — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Rosuvastatin’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Rosuvastatin column appears here.

See Every Supplement That Interacts With Rosuvastatin

This page covers Lathyrus only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Rosuvastatin page lists 63 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (major), Grapefruit (major), Siberian Cocklebur (major) and Wine (major).

By severity: 5 major · 48 moderate · 10 minor.

From our pharmacist’s overview on the Rosuvastatin page

“Rosuvastatin (Crestor, Ezallor) is a statin taken daily for years to lower cholesterol, and its supplement list deserves real scrutiny, not a quick skim. Five of the 63 ingredients on file carry a major rating, headed by grapefruit, which can raise statin blood levels, and by heavy drinking, since beer and wine compound the strain this…”

About Lathyrus

What is Lathyrus?

  • Food and famine crop in some regions
  • Source of dietary protein
  • Traditional folk remedies
  • Animal fodder

Lathyrus most often refers to the grass pea (Lathyrus sativus), a hardy legume eaten as food in parts of Asia and Africa. While it is nutritious, heavy or prolonged consumption is linked to a serious neurological disorder called lathyrism, so it is not recommended as a dietary supplement. There is no good evidence supporting Lathyrus for any specific health condition.

Lathyrus sativus · Fabaceae · Seeds (grass pea / chickling pea); occasionally other plant parts · Dried seeds, flour, cooked legume dishes; not commonly sold as a standardized supplement

An interaction check asks whether these two react with each other — it does not ask whether Lathyrus is a good idea for someone in your situation. Here is what our Lathyrus record says about it on its own.

Lathyrus: dosing

There is no established or standardized supplement dose for Lathyrus, and it is not recommended as a supplement. Because of the toxin it contains, larger and more frequent intake increases the risk of harm.If grass pea is part of your traditional diet, it is safest to eat it in moderation as one of many foods, and to prepare it by soaking and boiling. Do not rely on it as a main protein source.

About Rosuvastatin

What Is Rosuvastatin Used For?

Brand names: Crestor, Ezallor

Rosuvastatin tablets are used alongside diet changes to lower LDL-C ("bad" cholesterol), total cholesterol, and triglycerides (blood fats), and to raise HDL-C ("good" cholesterol) in adults with high cholesterol or mixed cholesterol problems. They are also used in adults with very high triglycerides, a condition called primary dysbetalipoproteinemia (Type III, a genetic fat-metabolism disorder), and to slow the buildup of plaque in arteries (atherosclerosis).

In people without established heart disease but with multiple risk factors, rosuvastatin tablets can reduce the risk of heart attack, stroke, and procedures to open blocked arteries. For children and teens aged 8 and older with heterozygous familial hypercholesterolemia (HeFH, an inherited high-cholesterol condition), the tablet form is used to lower LDL-C after diet alone has not worked. Crestor tablets are also approved to treat homozygous familial hypercholesterolemia (HoFH, a more severe inherited form) in adults and in children aged 7 and older.

Most-Reported Side Effects for Rosuvastatin

From FAERS, the FDA’s public side-effect reporting system (229,715 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 12,432 reports
