HelloPharmacist Scorecard of Pfaffia Suma Root Tincture by Barlow Herbal

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

This tincture contains one active ingredient: suma root, a tropical plant used traditionally in herbal medicine. Suma is delivered as a liquid extract in a base of cane alcohol.

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 Suma product and its label doesn't state a use — see Suma'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.

We don't have effectiveness data on file for suma root. The evidence supporting its use isn't established in the data we hold.

The evidence, ingredient by ingredient Suma

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 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.

Suma is generally well tolerated when taken by mouth, and no adverse effects have been reported in practice. However, safety data in humans are limited, and a thorough safety evaluation hasn't been done.

When suma root powder is inhaled, it can trigger allergic asthma symptoms in susceptible people — but swallowing the tincture carries a different risk profile. Pregnancy and breastfeeding are specific concerns: safety data aren't strong enough to recommend use during either, so it's best avoided then.

Side effects, ingredient by ingredient Suma

Meds to double-check

No known interactions
Known Interaction Concern · database check

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the suma ingredient we checked. Still, check your exact medications with the search tool before you start, or ask your pharmacist if you're unsure.
