Drug & supplement interaction

Artemisia Herba-alba + Colesevelam

Colesevelam brand names: WelChol, Lodalis.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Artemisia Herba-alba and Colesevelam 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 label for Colesevelam states a food rule worth keeping to, and 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

Artemisia Herba-alba and Colesevelam

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 Colesevelam and Artemisia Herba-alba 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.

Artemisia Herba-alba safety at a glance

Artemisia Herba-al... overall Use caution Limited human safety data and the herb may affect blood sugar, so use carefully and under professional guidance.
Pregnancy Avoid Avoid during pregnancy; Artemisia species are traditionally linked to uterine stimulation and lack safety data.
Breastfeeding Avoid No reliable safety information is available, so avoid 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 Colesevelam

Interactions in our licensed database are recorded against drug classes, not just single drug names. Colesevelam is filed under a single classification — oral drugs. Artemisia Herba-alba has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Colesevelam’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 Artemisia Herba-alba and Colesevelam 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. 2 of them are worth acting on rather than waiting out — marked below.

Effects for Colesevelam come from the ADVERSE REACTIONS section of its FDA label; effects for Artemisia Herba-alba come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 2,014 voluntary FDA FAERS reports for Colesevelam 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.

How to take them

Some Colesevelam Products Have a Food Rule — Artemisia Herba-alba Should Not Break It

At least one FDA label for a product containing Colesevelam says to take it with food. If you take Artemisia Herba-alba on an empty stomach out of habit, keep them separate — and take Colesevelam with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Colesevelam products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Colesevelam hydrochloride should be taken as follows ( 2.2 , 2.4 ): Tablets Take 6 tablets once daily or 3 tablets twice daily with a meal and liquid.

From the Dosage and Administration section of the FDA label we read for Colesevelam — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Overlapping uses

What Colesevelam Is Prescribed For, and What Artemisia Herba-alba Has Been Studied For

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

Colesevelam is prescribed for: Colesevelam is used alongside diet and exercise to reduce high LDL cholesterol (the "bad" cholesterol) in adults with primary hyperlipidemia (high cholesterol). It is also approved to lower LDL cholesterol in boys and girls aged 10–17 who have heterozygous familial hypercholesterolemia (HeFH) — an inherited condition that causes very high cholesterol — when diet and lifestyle changes alone haven't worked. Colesevelam tablets and oral suspension (Welchol and colesevelam hydrochloride products) are also used to improve blood sugar control in adults with type 2 diabetes, as an add-on to diet and exercise. Colesevelam is not for type 1 diabetes or diabetic ketoacidosis.

Artemisia Herba-alba has been studied for:

  • Diabetes studied, not established Artemisia Herba-alba has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Artemisia Herba-alba for diabetes

    It is unclear if oral Artemisia herba-alba is beneficial in patients with diabetes.

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 Colesevelam on your own; if you are taking Artemisia Herba-alba 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 Colesevelam page

“Colesevelam (WelChol, Lodalis) lowers cholesterol by binding bile acids in your gut, and every one of the 17 supplements on this list can interfere with how oral medicines are absorbed in that same territory. I would treat this list with genuine care, and the place to start is activated charcoal, the only major-rated entry.”

About Artemisia Herba-alba

What is Artemisia Herba-alba?

Artemisia Herba-alba
  • Diabetes and blood sugar
  • Digestive upset
  • Intestinal worms and parasites
  • Cough and respiratory complaints
  • Antimicrobial uses

Artemisia herba-alba is a desert shrub used in North African and Middle Eastern folk medicine, most often for digestion, diabetes, and parasites. Human evidence is very limited, and most findings come from lab or animal studies, so its benefits are unproven. Because it can affect blood sugar and contains potentially toxic compounds, talk with your pharmacist or doctor before using it.

Artemisia herba-alba · Asteraceae · Aerial parts (leaves and flowering tops); sometimes bark and roots; essential oil · Tea (infusion or decoction), dried herb, capsules, extracts, essential oil

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

Taking Artemisia Herba-alba and Colesevelam Together: Common Questions

Is it safe to take Artemisia Herba-alba with Colesevelam?
We do not list a known interaction between Artemisia Herba-alba and Colesevelam. 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 Artemisia Herba-alba and Colesevelam have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
Should I take Artemisia Herba-alba and Colesevelam at the same time of day?
At least one FDA label for a product containing Colesevelam says to take it with food. If you take Artemisia Herba-alba on an empty stomach out of habit, keep them separate and take Colesevelam with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Colesevelam products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Artemisia Herba-alba and Colesevelam 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 Artemisia Herba-alba in each. That is a conversation for your prescriber, especially if Colesevelam is being adjusted to a target.
How was the Artemisia Herba-alba and Colesevelam combination checked?
Interactions in our licensed database are recorded against drug classes. Colesevelam is filed under 1 classification, and Artemisia Herba-alba has documented interactions with 1 drug class — none of Colesevelam'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 Artemisia Herba-alba interact with any other medications?
Yes. Artemisia Herba-alba has 86 documented drug interactions in our database — Colesevelam 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 Colesevelam interact with any supplements?
Yes. Colesevelam has documented interactions with 17 supplements in our database — Artemisia Herba-alba is not one of them. The Colesevelam interaction page linked on this page lists every one, ranked by severity.
