What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Phyto-Gen Black Alder Bud is a one-ingredient liquid: black alder (Alnus glutinosa) bud extract. The extract is suspended in water, ethanol, and glycerin, which are the inactive ingredients that make up the liquid base.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Black Alder product and its label doesn't state a use — see Black Alder's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The facts we hold don't include any effectiveness ratings for black alder bud extract. That means the evidence for what it's meant to do isn't established in our data.

The evidence, ingredient by ingredient Black Alder

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Black alder has limited safety data on file. It may cause nausea or stomach upset, so if you do use it, keep it brief and watch how you feel.

The safety data advises against use during pregnancy because there isn't enough information to know it's safe. The same goes for breastfeeding — we don't have enough data to say it's okay, so avoiding it while nursing is the safer choice.

Side effects, ingredient by ingredient Black Alder

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Black Alder.
  • The most serious interaction on file is rated Moderate.
  • For scale: 2 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take cisplatin (Platinol-AQ) or doxorubicin (Adriamycin or generics), do not start this product without checking with your oncologist or pharmacist first — lab data suggests it may reduce how well these chemotherapy drugs work. No interactions are documented for other medications in our data, though the single ingredient we could check is limited in its overall safety profile.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

This is a single-ingredient herbal extract with very limited safety information. If you take cisplatin or doxorubicin or any other chemotherapy, you need to clear this with your oncologist or pharmacist before use.

Even if you're not on cancer treatment, talk it over with your doctor or pharmacist to make sure it's right for you.
