Cassia Auriculata and Hydroxyurea

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 Hydroxyurea and Cassia Auriculata 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 Hydroxyurea

Interactions in our licensed database are recorded against drug classes, not just single drug names. Hydroxyurea is filed under 2 classifications — antineoplastics, oral drugs. Cassia Auriculata has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and carbamazepine (tegretol) (moderate) — and none of Hydroxyurea’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 Hydroxyurea’s Own FDA Label Lists

This is not an interaction — none of it involves Cassia Auriculata. These are the most notable effects listed in the ADVERSE REACTIONS section of Hydroxyurea’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. 6 of them are worth acting on rather than waiting out — marked below.

  • Low magnesium Worth acting on
  • Anemia Worth acting on mentioned in 12.0% of FDA reports for Hydroxyurea
  • A low platelet count Worth acting on
  • Shortness of breath Worth acting on
  • A low white blood cell count Worth acting on
  • A higher chance of infection Worth acting on
  • Changes to your period
  • Dry skin
  • Weight gain
  • Pain in an arm or leg

From the ADVERSE REACTIONS section of the FDA label for Hydroxyurea. Read the label on DailyMed › Where a percentage is shown, it is the share of 21,027 voluntary FDA FAERS reports for Hydroxyurea that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Cassia Auriculata’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cassia Auriculata side to compare — that is a limit of the record, not a statement that Cassia Auriculata has no side effects.

From our pharmacist’s overview on the Hydroxyurea page

“People take hydroxyurea (Droxia, Hydrea, Siklos, Xromi) for serious reasons, most often sickle cell disease or certain blood cancers, and it only works if a steady dose reaches the bloodstream. That is exactly what nearly all 18 supplements listed here can undermine, so this page earns real vigilance rather than a skim.”

About Cassia Auriculata

What is Cassia Auriculata?

  • Blood sugar support
  • Skin health
  • Urinary complaints
  • Digestive upset
  • General tonic and antioxidant

Cassia auriculata (often called Tanner's cassia or Avaram) is a flowering shrub used in traditional Indian medicine, especially for blood sugar and skin concerns. Most evidence comes from laboratory and animal studies, so its benefits in people are not well proven. Talk to your pharmacist or doctor before using it, particularly if you take diabetes medicine or are pregnant.

Senna auriculata · Fabaceae · Flowers, leaves, bark, seeds, and roots · Tea, powder (churna), capsules, and traditional decoctions

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

Cassia Auriculata: dosing

There is no well-established, standardized dose for Cassia auriculata. Traditional use has varied widely depending on the part of the plant and the preparation, such as a tea made from dried flowers or a powder.Because supplements differ in strength, the best advice is to follow the directions on the product label and not exceed the recommended amount.
