Black Alder + Mechlorethamine Hydrochloride
Mechlorethamine Hydrochloride brand name: Valchlor.
We found no known interaction between Black Alder and Mechlorethamine Hydrochloride 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.
Black Alder and Mechlorethamine Hydrochloride
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 Mechlorethamine Hydrochloride and Black Alder 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.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Mechlorethamine Hydrochloride
Interactions in our licensed database are recorded against drug classes, not just single drug names. Mechlorethamine Hydrochloride is filed under 2 classifications — alkylating agents, topical drugs. Black Alder has documented interactions with 2 drug classes — the most serious being cisplatin (platinol-aq) (moderate) and doxorubicin (adriamycin, others) (moderate) — and none of Mechlorethamine Hydrochloride’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.

From our pharmacist’s overview on the Mechlorethamine Hydrochloride page
“Mechlorethamine (Valchlor) is a chemotherapy gel applied to the skin for a form of lymphoma, and the 10 supplements on this page split into two groups. Seven are antioxidants, everyday products like vitamin C and turmeric, which in theory could blunt how well an alkylating chemotherapy drug works.”

About Black Alder
What is Black Alder?
- Sore throat and mouth inflammation
- Skin wounds and irritation (topical)
- Fever and general aches (traditional)
- Digestive complaints
- Astringent for minor bleeding
Black Alder is a European tree whose bark and leaves have a long history in folk medicine, mainly as an astringent gargle or wound wash. There is very little modern human research to confirm any of these uses, and it can cause stomach upset, so it should be used cautiously and avoided during pregnancy and breastfeeding.
Alnus glutinosa · Betulaceae · Bark, leaves, and sometimes the catkins · Dried bark or leaf for tea, decoctions, tinctures, and gargles or mouth rinses
An interaction check asks whether these two react with each other — it does not ask whether Black Alder is a good idea for someone in your situation. Here is what our Black Alder record says about it on its own.

Traditional use involved making a tea or decoction from the dried bark or leaves, or using a diluted preparation as a gargle or skin wash.If you choose to use a product, follow the directions on the label and do not exceed the recommended amount.
