The Short Answer
Pasuchaca (Geranium dielsianum) is an Amazonian herb that demonstrates potent α-glucosidase inhibition with 96% maltase inhibition at tested concentrations. The plant shows blood sugar regulation potential through enzymatic inhibition and advanced glycation end-product protection via methylglyoxal scavenging.

Health Benefits
Origin & History
Natural habitat
Pasuchaca (Geranium dielsianum Knuth) is a small perennial herb native to Peru that grows 3-6 cm tall with distinctive 7-lobed palmate leaves. The aerial parts are harvested and typically extracted using 80% methanol or hydrated ethanol methods, yielding concentrated dihydroflavonol glycosides, particularly astilbin.
“Pasuchaca has been used in Peruvian traditional medicine for diabetes management, blood purification, and treating conditions like chronic diarrhea, hemorrhages, and inflammation. While described as a longstanding remedy by Laboratorios Fitofarma, the specific historical duration of use is undocumented.”Traditional Medicine
Scientific Research
No human clinical trials have been conducted on Pasuchaca. Available evidence is limited to in vitro studies, including one showing antiglycation activity where astilbin inhibited protein glycation across all stages (PMID: 41376105). Other laboratory studies demonstrated maltase inhibition and α-glucosidase inhibition, but human efficacy remains unproven.
Preparation & Dosage
Traditional preparation
No clinically studied human dosages exist. In vitro studies used extract concentrations of 0.00025-0.0005 mg/mL for enzyme inhibition, with astilbin content reaching 252.41 mg/g in 80% methanol extracts. Consult a healthcare provider before starting any new supplement.

How It Works
Mechanism of Action
Pasuchaca exerts its effects primarily through α-glucosidase enzyme inhibition, specifically targeting maltase with an IC50 of 0.028 mg/mL. The herb's bioactive compounds also scavenge methylglyoxal, a reactive dicarbonyl that forms advanced glycation end-products (AGEs). This dual mechanism supports glucose metabolism regulation and prevents protein glycation damage.
Clinical Evidence
Current evidence for Pasuchaca is limited to preliminary in vitro studies demonstrating enzymatic inhibition and antioxidant properties. Laboratory testing shows 96% maltase inhibition at specific concentrations, with superior methylglyoxal scavenging compared to control compounds. No human clinical trials have been conducted to validate these preliminary findings. The evidence remains at the preclinical stage and requires human studies for therapeutic confirmation.
Safety & Interactions
Safety data for Pasuchaca supplementation is extremely limited due to lack of human studies. No established side effect profile, drug interactions, or contraindications have been documented in scientific literature. Pregnant and breastfeeding women should avoid use due to insufficient safety data. Individuals taking diabetes medications should consult healthcare providers before use due to potential additive blood sugar lowering effects.

Frequently Asked Questions
What is the IC50 value for Pasuchaca's maltase inhibition?
Pasuchaca demonstrates maltase inhibition with an IC50 of 0.028 mg/mL in laboratory studies. This indicates relatively potent enzymatic inhibition at low concentrations, though human studies are needed for clinical relevance.
How does Pasuchaca prevent advanced glycation end-products?
Pasuchaca prevents AGE formation through methylglyoxal scavenging activity. In vitro studies show superior performance in neutralizing this reactive compound that causes protein glycation damage.
What percentage of maltase does Pasuchaca inhibit?
Laboratory studies demonstrate that Pasuchaca achieves 96% maltase inhibition at tested concentrations. This significant enzymatic inhibition suggests potential for blood sugar regulation support.
Are there any human clinical trials on Pasuchaca?
No human clinical trials have been conducted on Pasuchaca to date. All current evidence comes from preliminary in vitro laboratory studies, requiring human research for therapeutic validation.
Can Pasuchaca interact with diabetes medications?
While no documented interactions exist, Pasuchaca's α-glucosidase inhibition mechanism could potentially enhance blood sugar lowering effects of diabetes medications. Healthcare provider consultation is recommended before combining with antidiabetic drugs.
What is the antioxidant content of Pasuchaca and how does it compare to other herbs?
Pasuchaca contains 314–406 mg of gallic acid equivalents (GAE) per gram of dry matter, reflecting significant phenolic compound concentration. This antioxidant profile positions it comparably to other traditional Andean herbs used for metabolic support, though direct head-to-head studies with specific antioxidant reference standards remain limited.
Is Pasuchaca safe for people with type 2 diabetes taking prescription glucose-lowering medications?
While Pasuchaca shows promise for blood sugar regulation through α-glucosidase inhibition, there is insufficient clinical evidence to confirm safety when combined with prescription diabetes medications. Individuals taking medications like metformin or sulfonylureas should consult their healthcare provider before using Pasuchaca, as additive glucose-lowering effects could theoretically increase hypoglycemia risk.
What is the quality of evidence supporting Pasuchaca's effectiveness for blood sugar control?
Current evidence for Pasuchaca is primarily from in vitro and preliminary studies, with the 96% maltase inhibition data derived from laboratory concentrations rather than human clinical trials. No published human studies have yet demonstrated bioavailability, actual blood sugar impact, or effective dosing in real-world conditions, making recommendations speculative at this stage.
