Drug & supplement interaction

Bupleurum + Lithium Carbonate (prescription drug)

Lithium Carbonate (prescription drug) brand names: Eskalith, Lithium Carbonate.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Bupleurum and Lithium Carbonate (prescription drug) 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Bupleurum and Lithium Carbonate (prescription drug)

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 Lithium Carbonate (prescription drug) and Bupleurum 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.

Bupleurum safety at a glance

Bupleurum overall Use caution Generally used short-term in formulas, but it has been linked to rare lung and liver problems and quality varies.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety information, so it is best avoided while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Lithium Carbonate (prescription drug)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lithium Carbonate (prescription drug) is filed under 7 classifications — including antipsychotic drugs, serotonergic drugs, serotonergic drugs. Bupleurum has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and immunosuppressants (moderate) — and none of Lithium Carbonate (prescription drug)’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 to actually watch for

No Interaction Found — But Data Suggests Bupleurum and Lithium Carbonate (prescription drug) May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

Reported for Bupleurum but not commonly for Lithium Carbonate (prescription drug): numbness or tingling, liver problems and a higher chance of infection.

Effects for Lithium Carbonate (prescription drug) come from the ADVERSE REACTIONS section of its FDA label; effects for Bupleurum come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 42,295 voluntary FDA FAERS reports for Lithium Carbonate (prescription drug) that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Lithium Carbonate (prescription drug) Is Prescribed For, and What Bupleurum Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Lithium Carbonate (prescription drug) is a prescription medicine with approved uses on its FDA label. Bupleurum is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Lithium Carbonate (prescription drug) is prescribed for: Lithium is used for bipolar disorder. It treats manic episodes and is also used as maintenance treatment to reduce how often manic episodes happen and how intense they are. Newer lithium labels (tablets, capsules and oral solution) describe use alone (monotherapy) for bipolar I disorder. This includes acute manic and mixed episodes and maintenance treatment in patients 7 years and older.

Read the rest of what Lithium Carbonate (prescription drug) is prescribed for

Some older lithium carbonate extended-release tablet and capsule labels describe use in adults with manic episodes of bipolar disorder (manic-depressive illness) and for maintenance.

Bupleurum has been studied for:

  • Depression studied, not established Bupleurum has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Bupleurum for depression

    Oral bupleurum has only been evaluated in combination with other ingredients; its effect when used alone is unclear.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Lithium Carbonate (prescription drug) on your own; if you are taking Bupleurum for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Lithium Carbonate (prescription drug) page

“Lithium carbonate (Eskalith) steadies mood in bipolar disorder, but it works within a narrow blood-level window, meaning a small shift up risks toxicity and a shift down risks relapse. The 189 supplements and herbs listed here therefore call for genuine vigilance.”

About Bupleurum

What is Bupleurum?

Bupleurum
  • Liver and digestive support
  • Cold, flu, and fever
  • Inflammation
  • Stress and mood
  • Immune support

Bupleurum (Chai Hu) is a root used in traditional Chinese medicine, usually as part of multi-herb formulas, for liver, digestive, and fever-related complaints. High-quality human evidence for its benefits is limited, and it has been linked to lung and liver problems in some reports, so use it cautiously and only under professional guidance.

Bupleurum chinense · Apiaceae · Root · Capsules, tablets, dried root, teas, tinctures, and traditional Chinese herbal formulas

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

Bupleurum: dosing

There is no well-established standard dose of Bupleurum. Do not exceed the recommended amount, and avoid long-term use without professional guidance.

Taking Bupleurum and Lithium Carbonate (prescription drug) Together: Common Questions

Is it safe to take Bupleurum with Lithium Carbonate (prescription drug)?
We do not list a known interaction between Bupleurum and Lithium Carbonate (prescription drug). That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Bupleurum and Lithium Carbonate (prescription drug) have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Bupleurum and Lithium Carbonate (prescription drug) used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Bupleurum in each. That is a conversation for your prescriber, especially if Lithium Carbonate (prescription drug) is being adjusted to a target.
How was the Bupleurum and Lithium Carbonate (prescription drug) combination checked?
Interactions in our licensed database are recorded against drug classes. Lithium Carbonate (prescription drug) is filed under 7 classifications, and Bupleurum has documented interactions with 3 drug classes — none of Lithium Carbonate (prescription drug)'s classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Bupleurum interact with any other medications?
Yes. Bupleurum has 327 documented drug interactions in our database — Lithium Carbonate (prescription drug) is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Lithium Carbonate (prescription drug) interact with any supplements?
Yes. Lithium Carbonate (prescription drug) has documented interactions with 189 supplements in our database — Bupleurum is not one of them. The Lithium Carbonate (prescription drug) interaction page linked on this page lists every one, ranked by severity.
