HelloPharmacist Scorecard of Tejo Root by H & Natural
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.
What’s inside
Full disclosure
Tejo Root contains two active ingredients. Pectin is a soluble fiber extracted from plants, used to support cholesterol levels.
Mexican hawthorn is a botanical extract traditionally used for heart and circulation support. There are no inactive ingredients listed in this product.
Does it work?
Moderate evidence
Pectin is possibly effective for high cholesterol (hypercholesterolemia), but the evidence for blood sugar control (impaired glucose tolerance, or prediabetes) and radiation exposure is insufficient. Mexican hawthorn's evidence for angina, anxiety, irregular heartbeat, atherosclerosis, cardiovascular disease, and cognitive function is insufficient to rate — we don't have enough reliable data to know whether it works for these conditions.
How safe is it?
Well-documented data
Pectin is generally well tolerated and commonly appears in food. The most frequent side effects are gas, loose stools, diarrhea, and mild cramps.
Rarely, pectin can trigger allergic reactions, including severe ones (anaphylaxis) in sensitive people, and breathing problems from inhaling pectin dust. Mexican hawthorn is generally well tolerated in studies but has rarely caused serious allergic reactions affecting multiple organs, kidney damage, or heart rhythm problems (palpitations, fast heart rate).
The safety data advises against use of Mexican hawthorn during pregnancy and while breastfeeding.
Meds to double-check
Major interaction found
Before taking Tejo Root, double-check with your doctor or pharmacist if you take nitrates or drugs for erectile dysfunction (phosphodiesterase-5 inhibitors) — Major interaction risk. Also flag any beta-blockers, blood thinners (anticoagulants or antiplatelet drugs), calcium channel blockers, lovastatin, tetracycline antibiotics, or digoxin — these carry Moderate interaction risks.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
Tejo Root may be worth considering if you're interested in cholesterol or heart support, but the evidence for Mexican hawthorn's effectiveness is not established. If you have heart disease, take blood pressure or heart medications, or use antibiotics or cholesterol drugs, talk with your doctor or pharmacist before starting this — the interactions can weaken your medications or lower your blood pressure too much.
Pregnant or breastfeeding? Mexican hawthorn is not recommended; check with your healthcare provider about pectin.

For each ingredient in Tejo Root with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Mexican Hawthorn
Nitrates
Theoretically, concomitant use might cause additive coronary vasodilatory effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.
Phosphodiesterase-5 Inhibitors
Theoretically, concomitant use might result in additive vasodilation and hypotension.
Hawthorn might inhibit PDE-5 and cause vasodilation.
Anticoagulant/Antiplatelet Drugs
Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that hawthorn can inhibit platelet aggregation. However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract. However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans.
Beta-Blockers
Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.
Some evidence shows that hawthorn might lower blood pressure and heart rate.
Calcium Channel Blockers
Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.
Digoxin (Lanoxin)
Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.
Hawthorn appears to improve cardiac output; however, hawthorn does not appear to affect digoxin pharmacokinetics. Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels.
Pectin
Digoxin (Lanoxin)
Theoretically, pectin might reduce the absorption of digoxin, potentially decreasing its effectiveness.
A small clinical study shows that taking digoxin with a kaolin-pectin suspension reduces the absorption of digoxin by about 62%. It is unclear if these effects are due to pectin, kaolin, or the combination.
Lovastatin (Mevacor)
Theoretically, pectin might reduce the absorption of lovastatin, potentially decreasing its effectiveness.
Case reports suggest that concomitant use of pectin and lovastatin might reduce the cholesterol-lowering effect of lovastatin, possibly due to reduced intestinal absorption of lovastatin.
Tetracycline Antibiotics
Theoretically, pectin might reduce the absorption of tetracycline antibiotics, potentially decreasing their effectiveness.
A small clinical study shows that taking tetracycline with bismuth subsalicylate in a kaolin-pectin suspension reduces the absorption of tetracycline by about 34%. It is unclear if these effects are due to pectin, kaolin, bismuth subsalicylate, or the combination.
