The bottom line No known interaction

We found no known interaction between Ayurveda and Diltiazem 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.

Ayurveda and Diltiazem

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 Diltiazem and Ayurveda 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 Ayurveda at all — not against Diltiazem, 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.

Ayurveda safety at a glance

Ayurveda overall Use caution Some Ayurvedic products have been found to contain toxic heavy metals or undisclosed drugs, so quality and source matter greatly.
Pregnancy Avoid Many Ayurvedic herbs and formulas are not proven safe in pregnancy and some may carry contamination risks, so avoid unless cleared by your doctor.
Breastfeeding Avoid Safety during breastfeeding is not established, so it is best to avoid Ayurvedic remedies unless a healthcare provider approves.

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

What to actually watch for

What Diltiazem’s Own FDA Label Lists

This is not an interaction — none of it involves Ayurveda. These are the most notable effects listed in the ADVERSE REACTIONS section of Diltiazem’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.

  • Bleeding in the gut Worth acting on
  • A slow heartbeat Worth acting on
  • Shortness of breath Worth acting on mentioned in 9.6% of FDA reports for Diltiazem
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on
  • A severe skin reaction Worth acting on
  • Chest pain Worth acting on
  • Kidney problems Worth acting on
  • Raised blood pressure Worth acting on
  • Hives Worth acting on

Showing the 10 most notable of 41 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 Diltiazem. Read the label on DailyMed › Where a percentage is shown, it is the share of 34,400 voluntary FDA FAERS reports for Diltiazem that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Ayurveda’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Ayurveda side to compare — that is a limit of the record, not a statement that Ayurveda has no side effects.

See Every Supplement That Interacts With Diltiazem

This page covers Ayurveda only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Diltiazem page lists 260 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Coleus (major) and Grapefruit (major).

From our pharmacist’s overview on the Diltiazem page

“Someone on diltiazem (Cardizem, Tiazac) is usually managing blood pressure, angina, or a fast heart rhythm, so this list deserves genuine care. Seven of the 260 ingredients on file carry a major rating, and two of those are things people actually buy: grapefruit, which blocks the enzyme that clears diltiazem and can push its blood leve…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Ayurveda is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Ayurveda reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Ayurveda and Diltiazem records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Ayurveda

What is Ayurveda?

  • General wellness and prevention
  • Digestive complaints
  • Stress and sleep
  • Joint and muscle discomfort
  • Skin conditions
  • Chronic conditions like arthritis or diabetes

Ayurveda is one of the world's oldest whole-body healing systems, originating in India, that uses herbs, diet, lifestyle, and body therapies to support health. Some individual Ayurvedic herbs have promising research, but the system as a whole is not well proven by modern science, and certain Ayurvedic products have been found to contain heavy metals like lead, mercury, and arsenic. Always buy from trusted sources and talk to your pharmacist or doctor before starting.

Not applicable (Ayurveda is a traditional medicine system, not a single plant) · Herbal powders, tablets, capsules, teas, oils, and combination formulas; also diet, massage, and lifestyle practices

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

Ayurveda: dosing

There is no single standardized dose for Ayurveda, because it covers many different herbs, formulas, and practices. Doses vary widely between products and between practitioners.If you choose to use an Ayurvedic product, follow the directions on the label and do not exceed the recommended amount.

About Diltiazem

What Is Diltiazem Used For?

Brand names: Cardizem, Cardizem SR, Diltiaz SR, Cardizem CD, Tiazac, Diltiaz XT, Diltiaz CD, Dilacor, Diltiaz, Cardizem LA, Dilacor XR, Cartia XT, Tiamate, Adizem-SR, Adizem-XL, Angitil SR, Angitil XL, Calcicard CR, Dilcardia SR, Dilzem SR, Dilzem XL, Slozem, Tildiem LA, Tildiem Retard, Viazem XL, Zemtard 120XL, Zemtard 180XL, Zemtard 240XL, Zemtard 300XL

Oral extended-release forms of diltiazem — including Matzim LA, Cardizem LA, Cartia, Cartia XT, Tiadylt ER, and various generic capsules and tablets — are used to treat high blood pressure (hypertension) and chronic stable angina (chest pain brought on by activity). Some capsule formulations, including Cartia, Cartia XT, and certain generics, are also approved for angina due to coronary artery spasm (sudden chest pain caused by a sudden tightening of a coronary artery).

Injectable forms of diltiazem are used in hospital settings to temporarily slow a dangerously fast heart rate in atrial fibrillation or atrial flutter (rapid, irregular heart rhythms), and to restore a normal heart rhythm in paroxysmal supraventricular tachycardia (PSVT) — sudden episodes of a very fast but regular heartbeat originating above the heart's lower chambers.

Most-Reported Side Effects for Diltiazem

From FAERS, the FDA’s public side-effect reporting system (34,400 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dyspnea 3,309 reports
Fatigue 2,733 reports
Nausea 2,454 reports
Dizziness 2,174 reports
Diarrhea 2,113 reports
