Indian Cassia and Gabapentin

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 Gabapentin and Indian Cassia 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.

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.

Indian Cassia overall Use caution Generally safe as a food spice, but concentrated supplements and oils are not well studied.
Pregnancy Use caution Food amounts are likely fine, but avoid medicinal or concentrated doses without medical advice.

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

How we checked

Why No Interaction Is Listed for Gabapentin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Gabapentin is filed under 4 classifications — including anticonvulsants, cns depressants, oral drugs. Indian Cassia has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and diuretic drugs (moderate) — and none of Gabapentin’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Gabapentin’s Own FDA Label Lists

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

  • Dependence or withdrawal symptoms Worth acting on
  • Thoughts of self-harm Worth acting on
  • Severe muscle breakdown Worth acting on
  • Memory problems Worth acting on
  • Low sodium Worth acting on
  • Unsteadiness Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • High blood sugar Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Gabapentin. Read the label on DailyMed › Where a percentage is shown, it is the share of 361,481 voluntary FDA FAERS reports for Gabapentin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Indian Cassia’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Indian Cassia side to compare — that is a limit of the record, not a statement that Indian Cassia has no side effects.

From our pharmacist’s overview on the Gabapentin page

“Gabapentin (Neurontin, Gralise) calms overactive nerves, which means it already slows your nervous system down, and that is exactly what 78 of the 106 supplements on this list also do. So the dominant risk here is sedation stacked on sedation, extra drowsiness at best and dangerously slowed breathing at worst, and with seven entries ra…”

About Indian Cassia

What is Indian Cassia?

  • Flavoring food
  • Digestive upset
  • Blood sugar support
  • Cold and cough relief
  • Antimicrobial

Indian Cassia (Cinnamomum tamala), also known as Indian bay leaf or tejpat, is an aromatic leaf used widely as a cooking spice and in traditional medicine across South Asia. Human evidence for its health benefits is very limited, so it is best enjoyed as a culinary spice rather than relied on to treat any condition. Used as food it is generally well tolerated, but talk to your pharmacist or doctor before using concentrated supplements or oils.

Cinnamomum tamala · Lauraceae · Leaves (often called tejpat or Indian bay leaf) and bark · Whole dried leaves used in cooking, powder, tea, and essential oil

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

Indian Cassia: dosing

There is no established standardized medicinal dose for Indian Cassia. As a spice, people use small amounts of the dried leaf to flavor cooking, which is the most common and best-understood use.For capsules, powders, teas, or oils, follow the directions on the product label, since strength varies between products.

About Gabapentin

What Is Gabapentin Used For?

Brand names: Neurontin, Gralise

Gabapentin (brands include Neurontin, Relgaabi, Gabarone, Gralise, and Horizant) is primarily used to manage postherpetic neuralgia (PHN) — the nerve pain that lingers after a shingles outbreak — in adults. Neurontin, Relgaabi, Gabarone, and gabapentin capsules, tablets, and oral solution are also used as add-on therapy for partial onset seizures (a type of epilepsy) in adults and children aged 3 and older.

Horizant (gabapentin enacarbil extended-release tablet) has two specific approvals: treatment of moderate-to-severe primary restless legs syndrome (RLS) in adults, and management of postherpetic neuralgia in adults. Horizant is not recommended for people who need to sleep during the day and stay awake at night. Gralise is approved only for postherpetic neuralgia and cannot be substituted for other gabapentin products due to its different release profile.

Most-Reported Side Effects for Gabapentin

From FAERS, the FDA’s public side-effect reporting system (361,481 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 24,972 reports
Nausea 22,728 reports
Diarrhea 18,114 reports
