HelloPharmacist Scorecard of Shan Zha by Herbal Terra
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
Shan Zha is a single-ingredient liquid supplement containing hawthorn fruit extract — a traditional herbal used in cardiovascular and heart health contexts. The extract is delivered in a liquid base with alcohol, water, and glycerin as inactive ingredients.
Does it work?
Couldn't assess
The effectiveness data for hawthorn in Shan Zha is not established in our records. Evidence is listed as insufficient to rate its use for angina, anxiety, arrhythmia, atherosclerosis, cardiovascular disease, and cognitive function.
This doesn't mean it doesn't work — it means rigorous clinical evidence for these uses hasn't been established yet.
How safe is it?
Well-documented data
Hawthorn is generally well tolerated when used appropriately, though heart conditions need medical supervision. Serious adverse effects are rare but have been reported — very rarely, multiorgan hypersensitivity reactions affecting the kidneys.
Less serious effects in studies include palpitations, rapid heartbeat, and breathing changes in a small number of patients. Because there isn't enough safety information, this product should be avoided during pregnancy and while breastfeeding — talk to your doctor or pharmacist if you're in either situation.
Meds to double-check
Major interaction found
Do not use this product with nitrates or phosphodiesterase-5 inhibitors — the risk of severe low blood pressure is Major. Also double-check beta-blockers, calcium channel blockers, blood thinners (anticoagulants and antiplatelet drugs), and digoxin before you start, as hawthorn may intensify their effects.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Shan Zha is a single hawthorn extract intended for heart health, but it's not appropriate with most cardiac or blood pressure medications without medical approval. If you have a heart condition or take any prescription medications, check with your pharmacist before starting.
Pregnant or breastfeeding — skip this one and talk to your doctor first.

Shan Zha by Herbal Terra Drug Interactions
HelloPharmacist Interaction Report
Shan Zha by Herbal Terra contains hawthorn fruit extract, which interacts with several cardiovascular and blood pressure medications.
The most serious concerns are with nitrates (like nitroglycerin) and phosphodiesterase-5 inhibitors (like sildenafil/Viagra) — both carry Major severity ratings. Hawthorn can add to their blood vessel-relaxing effects and cause a dangerous drop in blood pressure.
Read the full breakdown — every affected drug type, severity by severity
Moderate interactions exist with beta-blockers, calcium channel blockers, and blood thinners (anticoagulants and antiplatelet drugs). Hawthorn may enhance their blood pressure or heart rate effects, or theoretically increase bleeding risk.
It may also amplify the effects of digoxin (a heart medication), which carries its own risks if levels get too high.
Altogether, these interactions span 190 individual medications. Because this product affects the heart and blood pressure, do not use it alongside heart or blood pressure drugs without checking with your pharmacist or doctor first.

For each ingredient in Shan Zha with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Crataegus pinnatifida Fruit Extract, Dry
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.
