No Known Interaction
The bottom line No known interaction

We found no known interaction between Solomon's Seal and Omalizumab in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Solomon's Seal and Omalizumab

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Omalizumab and Solomon's Seal in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Omalizumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Omalizumab is filed under a single classification — immunosuppressants. Solomon's Seal has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), chlorpropamide (diabinese) (moderate) and insulin (moderate) — and none of Omalizumab’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Solomon's Seal Itself Has Been Linked To

This is not an interaction — nothing below involves Omalizumab. It is the side-effect record for Solomon's Seal on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Solomon's Seal, this list is the first place to look.

  • Diarrhea / Nausea Additional detail

    “A thorough evaluation of safety outcomes has not been conducted. Orally, long-term use of Solomon's seal has been reported to cause gastrointestinal irritation. Use of large doses or overdoses may cause nausea, diarrhea, and other gastrointestinal complaints (18).”

Everything above comes from the Natural Medicines adverse-effect record for Solomon's Seal — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Omalizumab’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Omalizumab column appears here.

From our pharmacist’s overview on the Omalizumab page

“None of the 53 supplements on file for omalizumab (Xolair) carries a major rating, so this is a list to read with steady attention rather than alarm. Xolair treats allergic asthma and chronic hives by calming part of the immune system, and every entry here pulls the other way: these are immune-stimulating products, echinacea and astrag…”

About Solomon's Seal

What is Solomon's Seal?

Solomon's Seal
  • Joint and muscle discomfort
  • Tendon and ligament injuries
  • Inflammation
  • Digestive complaints
  • Skin and wound care
  • Dry cough and throat irritation

Solomon's Seal is a traditional herb whose root has long been used for joint, tendon, and muscle complaints, but high-quality human studies are largely lacking. There is not enough reliable evidence to confirm it works for any specific condition, so use it cautiously and talk with your pharmacist or doctor first.

Polygonatum multiflorum · Asparagaceae · Rhizome (root) and sometimes the whole plant · Capsules, dried root, teas, tinctures, powders, and topical salves

An interaction check asks whether these two react with each other — it does not ask whether Solomon's Seal is a good idea for someone in your situation. Here is what our Solomon's Seal record says about it on its own.

Solomon's Seal: dosing

There is no standardized, scientifically established dose for Solomon's Seal. Products vary widely in strength and form, so amounts on labels are not based on strong clinical research.If you choose to use it, follow the directions on the product label and do not exceed the suggested amount. Because doses are not well studied, it is wise to start low.

About Omalizumab Injection

What Is Omalizumab Injection Used For?

Brand name: Xolair

Xolair is used for several allergy-driven conditions. It treats moderate to severe persistent asthma in adults and children 6 and older whose symptoms aren't controlled by inhaled steroids alone and who test positive for a year-round airborne allergen. It is also used as an add-on maintenance treatment for chronic rhinosinusitis with nasal polyps (ongoing sinus inflammation with polyp growths) in adults 18 and older who haven't responded well to nasal corticosteroids.

Xolair is also approved to reduce allergic reactions — including anaphylaxis — from accidental food exposure in adults and children aged 1 and older with IgE-mediated food allergy. It must be used alongside strict food avoidance, and it is not a substitute for emergency treatment like epinephrine. Finally, Xolair treats chronic spontaneous urticaria (persistent hives with no identified trigger) in adults and adolescents 12 and older who still have symptoms despite antihistamine treatment.
