Manchurian Thorn and Theophylline

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 Theophylline and Manchurian Thorn 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 Theophylline

Interactions in our licensed database are recorded against drug classes, not just single drug names. Theophylline is filed under 6 classifications — including methylxanthines, cytochrome p450 1a2 (cyp1a2) substrates, cytochrome p450 1a2 (cyp1a2) substrates. Manchurian Thorn has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and hepatotoxic drugs (moderate) — and none of Theophylline’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 Theophylline’s Own FDA Label Lists

This is not an interaction — none of it involves Manchurian Thorn. These are the most notable effects listed in the ADVERSE REACTIONS section of Theophylline’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 9 of them are worth acting on rather than waiting out — marked below.

  • Severe muscle breakdown Worth acting on
  • Trouble passing urine Worth acting on
  • Low potassium Worth acting on
  • High blood sugar Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • Heartburn

Showing the 10 most notable of 25 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Theophylline. Read the label on DailyMed › Where a percentage is shown, it is the share of 12,164 voluntary FDA FAERS reports for Theophylline that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Manchurian Thorn’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Manchurian Thorn side to compare — that is a limit of the record, not a statement that Manchurian Thorn has no side effects.

See Every Supplement That Interacts With Theophylline

This page covers Manchurian Thorn only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Theophylline page lists 126 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Ephedra (major), Sida Cordifolia (major), Adrafinil (moderate) and African Wild Potato (moderate).

By severity: 3 major · 89 moderate · 34 minor.

From our pharmacist’s overview on the Theophylline page

“Stop ephedra before anything else if you take theophylline (Theo-Dur, Slo-Bid, and others) for asthma or COPD. Both are stimulants, and together they raise the risk of serious heart and nervous system effects; Sida cordifolia, an herb that contains ephedrine, carries the same major rating.”

About Manchurian Thorn

What is Manchurian Thorn?

  • Blood sugar support
  • Joint and arthritis discomfort
  • Fatigue and general weakness
  • Digestive complaints
  • General tonic / adaptogen-like use

Manchurian Thorn (Aralia elata) is a thorny shrub or small tree used in traditional East Asian medicine, mainly for blood sugar, joint pain, and as a general tonic. Human evidence is very limited, so its benefits are not well proven. If you are considering it, talk with your pharmacist or doctor first, and avoid it during pregnancy and breastfeeding.

Aralia elata · Araliaceae · Root bark, stem bark, and sometimes young shoots · Decoctions (teas), tinctures, dried bark, capsules, and traditional food preparations of the young shoots

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