No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Sangre De Grado and Tofacitinib in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Sangre De Grado and Tofacitinib

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 Tofacitinib and Sangre De Grado 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Sangre De Grado at all — not against Tofacitinib, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Sangre De Grado overall Use caution It has a long history of traditional use but limited safety data for supplements, so use cautiously.

What to actually watch for

No Interaction Found — But Data Suggests Sangre De Grado and Tofacitinib May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Headache reported in 7.3% of FDA reports for Tofacitinib Additional detail

    Sangre De Grado

    “Orally, crofelemer (SP-303), a purified constituent of sangre de grado, seems to be well tolerated. No serious adverse effects have been reported in clinical studies.

From our pharmacist’s overview on the Tofacitinib page

“Supplements deserve genuine care alongside tofacitinib (Xeljanz, Xeljanz XR), a medicine that deliberately dials down the immune system to control conditions like rheumatoid arthritis and ulcerative colitis. Most of the interactions on this page run through the liver enzymes that clear the drug, meaning an herb can push its blood level…”

About Sangre De Grado

What is Sangre De Grado?

  • Diarrhea
  • Wound healing and skin sores
  • Digestive and stomach complaints
  • Insect bites and minor skin irritation
  • Sore throat and mouth ulcers

Sangre de Grado is a red tree sap from the Amazon rainforest used traditionally for diarrhea, wounds, and skin problems. Some of its compounds have been studied scientifically, and one purified ingredient (crofelemer) is used in a prescription anti-diarrhea drug, but the raw supplement itself has limited human research. Talk with a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a health condition.

Croton lechleri · Euphorbiaceae · Red sap (latex) from the bark of the tree · Liquid sap, tincture, topical gel or cream, capsules, and a purified extract (crofelemer) used in some medicines

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

Sangre De Grado: dosing

The right amount can depend on the form (liquid sap, tincture, gel, or capsule) and the concentration of the specific product.If you choose to use it, follow the directions on the product label and do not exceed the recommended amount.
