Hyacinth Bean and Sulfasalazine

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 Sulfasalazine and Hyacinth Bean 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 Hyacinth Bean at all — not against Sulfasalazine, 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.

Hyacinth Bean safety at a glance

Hyacinth Bean overall Use caution Cooked beans are widely eaten as food, but raw or undercooked beans can be toxic and concentrated supplement use is not well studied.
Pregnancy Use caution Eating well-cooked beans as food is likely fine, but medicinal or supplement amounts have not been proven safe and should be avoided.
Breastfeeding Use caution Little reliable safety information exists for medicinal use, so caution is advised beyond normal dietary amounts.

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

What Sulfasalazine’s Own FDA Label Lists

This is not an interaction — none of it involves Hyacinth Bean. These are the most notable effects listed in the ADVERSE REACTIONS section of Sulfasalazine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Kidney stones Worth acting on
  • Hearing loss Worth acting on
  • Severe muscle breakdown Worth acting on
  • Unsteadiness Worth acting on
  • Low blood sugar Worth acting on
  • Hallucinations Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on

Showing the 10 most notable of 43 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Sulfasalazine. Read the label on DailyMed › Where a percentage is shown, it is the share of 76,994 voluntary FDA FAERS reports for Sulfasalazine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Hyacinth Bean’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Hyacinth Bean side to compare — that is a limit of the record, not a statement that Hyacinth Bean has no side effects.

Everything else you take

See Every Supplement That Interacts With Sulfasalazine

This page covers Hyacinth Bean only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sulfasalazine page lists 39 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Alfalfa (moderate), Angelica Archangelica (moderate), Arrach (moderate) and Bergamot (moderate).

By severity: 1 major · 28 moderate · 10 minor.

From our pharmacist’s overview on the Sulfasalazine page

“Activated charcoal is the single major-rated risk for sulfasalazine (Azulfidine), because charcoal can bind the drug in the gut and cut how much your body absorbs, weakening a medicine people rely on for rheumatoid arthritis or ulcerative colitis. That entry alone earns this list of 39 supplements and herbs a careful read.”

About Hyacinth Bean

What is Hyacinth Bean?

  • Digestive upset and diarrhea
  • Nausea and poor appetite
  • General nourishment
  • Traditional summer 'heat' remedy
  • Mild fatigue or weakness

Hyacinth bean is a widely grown food legume that is also used in traditional medicine, mainly for digestive complaints. The cooked beans are eaten as food in many countries, but the raw or undercooked beans contain natural toxins and must be thoroughly cooked. Strong human evidence for its medicinal uses is lacking, so treat any health claims with caution and talk to your pharmacist or doctor.

Lablab purpureus · Fabaceae · Seeds (beans), pods, leaves, and flowers · Cooked beans, dried seeds, traditional decoctions, powders, and capsules

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

Hyacinth Bean: dosing

There is no well-established standardized medicinal dose for hyacinth bean. As a food, it is simply prepared and eaten like other dried beans after thorough soaking and cooking.For any supplement or traditional preparation, follow the directions on the product label and do not exceed the recommended amount.

About Sulfasalazine

What Is Sulfasalazine Used For?

Brand names: SAS, Azulfidine EN-Tabs, Azulfidine

Sulfasalazine tablets and delayed-release tablets are both used to treat mild to moderate ulcerative colitis, as add-on therapy in severe ulcerative colitis, and to help keep ulcerative colitis in remission between flares.

The delayed-release form — sold as Azulfidine EN-tabs and Sulfasalazine Delayed Release Tablets — is also approved for adults with rheumatoid arthritis who have not responded well enough to NSAIDs or salicylates, and for children with polyarticular-course juvenile rheumatoid arthritis who have had a similar inadequate response.
