Angelica Archangelica and Lomustine

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 Lomustine and Angelica Archangelica 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.

Angelica Archangelica safety at a glance

Angelica Archangel... overall Use caution Often used in food amounts, but medicinal doses are not well studied and can cause skin sensitivity to sunlight.
Pregnancy Avoid Traditionally thought to affect the uterus and not well studied; best avoided in medicinal amounts.
Breastfeeding Avoid Not enough safety data, so avoid medicinal use 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 Lomustine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lomustine is filed under 3 classifications — alkylating agents, antineoplastics, oral drugs. Angelica Archangelica has documented interactions with 1 drug class — the most serious being photosensitizing drugs (moderate) — and none of Lomustine’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

What Angelica Archangelica Itself Has Been Linked To

This is not an interaction — nothing below involves Lomustine. It is the side-effect record for Angelica Archangelica on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Angelica Archangelica, this list is the first place to look.

  • Sun sensitivity Additional detail

    “Orally or topically, Angelica archangelica might cause photosensitivity reactions. Patients who take Angelica archangelica orally or apply it topically should be advised to avoid prolonged exposure to the sun. Some constituents of the leaves have a strong irritant effect on the skin and mucous membranes, referred to as "angelica dermatitis" (18).”

Everything above comes from the Natural Medicines adverse-effect record for Angelica Archangelica — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Lomustine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Lomustine column appears here.

Everything else you take

See Every Supplement That Interacts With Lomustine

This page covers Angelica Archangelica only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Lomustine page lists 25 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Acerola (moderate), Alpha-lipoic Acid (moderate), Coenzyme Q10 (moderate) and Coffee Charcoal (moderate).

By severity: 1 major · 14 moderate · 10 minor.

From our pharmacist’s overview on the Lomustine page

“One capsule of lomustine (Ceenu) often carries a whole chemotherapy cycle, so supplements that keep it from being absorbed, or that blunt its cancer-fighting action, deserve more respect here than with most drugs. The lone major-rated interaction, activated charcoal, can bind lomustine in the gut and sharply cut how much reaches the body.”

About Angelica Archangelica

What is Angelica Archangelica?

Angelica Archangelica
  • Digestive upset and gas
  • Loss of appetite
  • Anxiety and restlessness
  • Mild respiratory complaints
  • Flavoring in foods and drinks

Angelica archangelica is a tall aromatic herb used traditionally for digestive complaints, poor appetite, and to flavor foods and liqueurs. Solid human evidence for its health benefits is limited, and its skin-sensitizing furanocoumarins mean caution is warranted. Pregnant and breastfeeding people should avoid it, and anyone considering it should check with a pharmacist or doctor first.

Angelica archangelica · Apiaceae (Umbelliferae) · Root, seeds (fruit), leaves, and essential oil · Tea, dried root, tincture, capsules, essential oil, and as a flavoring in liqueurs

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

Angelica Archangelica: dosing

There is no well-established standardized dose for Angelica archangelica. Traditional preparations include teas made from the dried root or seeds, tinctures, and capsules, but the amount of active compounds can vary widely between products.Because reliable dosing guidelines are lacking, the safest approach is to follow the directions on the product label and not exceed them. Avoid combining it with strong sun exposure or tanning.
