The bottom line No known interaction

We found no known interaction between Perilla and Balsalazide Disodium 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.

Perilla and Balsalazide Disodium

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 Balsalazide Disodium and Perilla 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 Perilla at all — not against Balsalazide Disodium, 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 Perilla Itself Has Been Linked To

This is not an interaction — nothing below involves Balsalazide Disodium. It is the side-effect record for Perilla on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Perilla, 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

    “Occupational asthma has been reported from breathing in smoke from roasted perilla seeds.”

  • A severe allergic reaction Worth acting on Additional detail

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

From our pharmacist’s overview on the Balsalazide Disodium page

“Balsalazide Disodium (Colazal, Giazo) only works if it reaches the colon intact, and the 17 supplement interactions on file all threaten that journey, so this list deserves real care. Every entry comes down to absorption of the oral dose.”

About Perilla

What is Perilla?

Perilla
  • Seasonal and food allergies
  • Asthma and airway inflammation
  • Atopic dermatitis (eczema)
  • Digestive upset
  • General anti-inflammatory support

Perilla is an Asian mint-family plant used in cooking and traditional medicine, mainly for allergy, breathing, and digestive complaints. Most human evidence is limited or preliminary, so it should not replace proven treatments. It is generally well tolerated as a food, but talk with your pharmacist or doctor before using concentrated supplements.

Perilla frutescens · Lamiaceae · Leaves, seeds, stem, and seed oil · Tea, capsules, seed oil, essential oil, dried leaf, culinary herb

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

Perilla: dosing

There is no well-established standard dose for perilla supplements. Products vary widely in their form and strength, from leaf teas to seed oil softgels to standardized extracts.The safest approach is to follow the directions on the product label and not to exceed them.
