Sweet Cicely and Dantrolene

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 Dantrolene and Sweet Cicely 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 Sweet Cicely at all — not against Dantrolene, 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.

Sweet Cicely safety at a glance

Sweet Cicely overall Use caution Likely safe in small culinary amounts, but medicinal use is poorly studied.
Pregnancy Avoid Not enough safety data, so it is best avoided in medicinal amounts during pregnancy.
Breastfeeding Avoid Safety has not been studied, so avoid medicinal use while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

  • Muscle weakness Worth acting on
  • Trouble swallowing Worth acting on
  • Blood clots Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Dantrolene. Read the label on DailyMed › Sweet Cicely’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Sweet Cicely side to compare — that is a limit of the record, not a statement that Sweet Cicely has no side effects.

From our pharmacist’s overview on the Dantrolene page

“People take dantrolene (Dantrium) for muscle spasticity from multiple sclerosis or spinal cord injury, and the drug already carries a boxed warning for liver injury. That is why its supplement interactions deserve genuine respect.”

About Sweet Cicely

What is Sweet Cicely?

  • Digestive upset and gas
  • Mild cough and chest complaints
  • As a natural sweetener for tart foods
  • Loss of appetite
  • General tonic

Sweet Cicely is a mild, anise-flavored garden herb traditionally used in cooking and folk remedies for digestion and coughs. There is very little modern scientific research to confirm any health benefits, but it is generally considered safe in food amounts. Talk to a pharmacist or doctor before using it as a medicine, especially if you are pregnant or breastfeeding.

Myrrhis odorata · Apiaceae · Leaves, seeds, and roots · Fresh or dried herb, tea, culinary herb, occasionally tincture

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

Sweet Cicely: dosing

There is no established, standardized medicinal dose for Sweet Cicely. Most use is culinary, where the fresh or dried leaves and seeds are added to food or steeped as a mild tea.If you choose to use a commercial Sweet Cicely product, follow the directions on the product label and do not exceed the recommended amount.

About Dantrolene

What Is Dantrolene Used For?

Brand names: Dantrium, Dantrium Intravenous

Dantrolene sodium capsules (Dantrium, Dantrolene Sodium) are used by mouth to control spasticity — painful or disabling muscle stiffness and spasms — caused by upper motor neuron disorders such as spinal cord injury, stroke, cerebral palsy, or multiple sclerosis. They are not used for muscle spasm from arthritis or other rheumatic conditions. Oral capsules are also used before and after surgery to prevent or reduce the risk of malignant hyperthermia in patients known to be susceptible.

For an active malignant hyperthermia crisis — a sudden, dangerous overheating of the muscles triggered by certain anesthetics — the intravenous (IV) forms are given in the hospital. Dantrium Intravenous, Revonto, Ryanodex, and Dantrolene injection are all indicated to treat a malignant hyperthermia crisis and may also be given before surgery to help prevent one in high-risk patients.
