HelloPharmacist Scorecard of S Spleen by Systemic Formulas Bio Function
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
Low disclosure
S Spleen contains 12 ingredients, including a proprietary blend. The active components include nettle (the aerial parts), which has traditionally been used for various conditions; lemon balm (melissa), a calming herb; boneset, used in folk remedies; and lysine, an amino acid.
The product also contains tissue factors from liver, pancreas, and spleen, along with amino acids isoleucine and leucine, and a botanical ingredient called pedra hume caa. The capsules are filled with gelatin, lactose, and stearic acid as inactive ingredients.
Does it work?
Couldn't assess
Nettle is rated possibly effective for diabetes management, though the evidence for hay fever, anemia, asthma, benign prostate enlargement, and gingivitis is insufficient to rate. Lemon balm is rated possibly effective for cold sores, stress, and depression.
Lysine is rated possibly effective for cold sores. Boneset and sweet gum lack reliable evidence for their listed uses (common cold, bronchitis, cough, and others).
The effectiveness of the proprietary blend and tissue factors is not established in our data.
How safe is it?
Well-documented data
Nettle is generally well tolerated when used as directed, but it should be avoided during pregnancy due to traditional concerns about effects on the uterus, and avoided while breastfeeding because safety has not been established. Lemon balm is well tolerated for short-term use, though high doses and long-term safety are not well studied; it should be avoided in pregnancy unless your doctor advises otherwise, and used with caution while breastfeeding.
Boneset should be used cautiously and short-term only because of possible liver-toxic alkaloids; it should be avoided in pregnancy and while breastfeeding. Lysine is generally well tolerated at typical doses, though high amounts may cause stomach upset; supplement safety in pregnancy and breastfeeding is not well studied.
Sweet gum can irritate skin and trigger allergic reactions, and should be avoided in pregnancy and breastfeeding.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking this product if you use blood thinners like warfarin, blood-sugar medications, water pills (diuretics), lithium, sedatives or other CNS depressants, thyroid replacement therapy, or drugs that induce the CYP3A4 enzyme (like carbamazepine). Also ask about 5-HT4 agonists before starting.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product combines herbs and amino acids traditionally used for immune and digestive support, but evidence is strongest only for nettle in diabetes and lemon balm for cold sores and mood. If you take blood thinners, diabetes medication, diuretics, lithium, CNS depressants, thyroid medication, or certain other drugs, you'll want to check your specific medications with your doctor or pharmacist before starting — the interactions are real and could affect how your drugs work.
Pregnant or breastfeeding individuals should talk with their healthcare provider first.

S Spleen by Systemic Formulas Bio Function Drug Interactions
HelloPharmacist Interaction Report
S Spleen by Systemic Formulas Bio Function has documented interactions through its nettle, lemon balm, boneset, and lysine content.
The most serious concern is a Moderate-severity interaction between nettle and warfarin (Coumadin), a blood thinner — nettle contains vitamin K, which in large amounts can reduce how warfarin works.
Read the full breakdown — every affected drug type, severity by severity
Nettle also has Moderate interactions with blood-sugar drugs (antidiabetes medications), water pills (diuretics), and lithium. Lemon balm carries Moderate interactions with CNS depressants (like sedatives and sleep aids) and thyroid hormone replacement therapy.
Boneset has a Moderate interaction with CYP3A4-inducing drugs, which may increase conversion of toxic alkaloids in boneset to harmful forms.
Lysine has a Minor interaction with 5-HT4 agonists. We could not check DL-methionine, RNA/DNA liver tissue factors, pedra hume caa, isoleucine, or pancreas and spleen tissue factors — no data on file for these ingredients.

For each ingredient in S Spleen 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.
Melissa
Cns Depressants
Theoretically, concomitant use of lemon balm might have additive effects with CNS depressant drugs.
Lemon balm seems to have CNS depressant activity in animals and in humans.
Thyroid Hormone
Theoretically, lemon balm might interfere with thyroid hormone replacement therapy.
In vitro, constituents of lemon balm extract bind to thyroid stimulating hormone (TSH), preventing TSH receptor-binding and leading to the inhibition of TSH-stimulated adenylate cyclase activity. In animals, lemon balm extract has been shown to decrease levels of circulating TSH and inhibit thyroid secretion.
Nettle
Antidiabetes Drugs
Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.
Diuretic Drugs
Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.
Lithium
Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.
Warfarin (Coumadin)
There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.
Boneset
Cytochrome P450 3A4 (Cyp3A4) Inducers
Boneset belongs to the genus Eupatorium, and many species of this genus contain hepatotoxic pyrrolizidine alkaloids (PAs). Hepatotoxic PAs are substrates of cytochrome P450 3A4 (CYP3A4). Theoretically, drugs that induce CYP3A4 might increase the conversion of PAs to toxic metabolites. Some drugs that induce CYP3A4 include carbamazepine (Tegretol), phenobarbital, phenytoin (Dilantin), rifampin, rifabutin (Mycobutin), and others.
Lysine Monohydrochloride
5-Ht4 Agonists
Theoretically, lysine may reduce the effects of 5-HT4 agonists.
Animal research suggests that L-lysine is a partial serotonin receptor 4 (5-HT4) antagonist and inhibits diarrhea induced by the 5-HT4 agonist, 5-hydroxytryptophane.
