Rauvolfia Vomitoria: Uses, Safety & Side Effects

The bottom line

Rauvolfia vomitoria is an African shrub whose root contains powerful alkaloids, including reserpine, that have historically been used for high blood pressure and agitation. Because these compounds can strongly affect blood pressure, mood, and the nervous system, the plant can cause serious side effects and is not a casual supplement. Always talk to a doctor or pharmacist before using it.

Overview

Rauvolfia vomitoria is a shrub or small tree that grows in tropical Africa. It is closely related to Rauvolfia serpentina, the Indian snakeroot plant that is famous as a source of the blood-pressure drug reserpine.

The root and root bark are the parts most often used. In traditional African medicine, preparations of the root have been used for many purposes, including calming agitation, lowering blood pressure, and treating fevers. Today the plant is also a commercial source of medicinal alkaloids.

Because Rauvolfia contains strong, drug-like compounds, it is very different from a mild kitchen herb. People should treat it with the same caution they would give a prescription medicine.

How it works

The root contains a group of compounds called indole alkaloids. The best known is reserpine, along with others such as ajmaline, ajmalicine, and yohimbine-related compounds.

Reserpine works by reducing the amount of certain chemical messengers (neurotransmitters like norepinephrine, dopamine, and serotonin) stored in nerve cells. This can lower blood pressure and have a calming or sedating effect. Some of the other alkaloids can affect the heart's rhythm and blood vessels.

Much of what we know comes from research on purified reserpine and from laboratory or animal studies of the plant. The exact effects of any given Rauvolfia supplement depend on how much active alkaloid it contains, which can vary a lot.

This is educational information, not medical advice — talk with your pharmacist or doctor before starting, stopping, or changing a supplement.

Safety & precautions

Rauvolfia vomitoria is not a gentle herb. Its alkaloids can lower blood pressure too much, slow the heart, and affect mood. Reserpine, in particular, has been linked to depression, sometimes severe.

People with low blood pressure, depression or other mood disorders, Parkinson's disease, stomach ulcers, heart rhythm problems, or kidney disease should avoid it unless a doctor advises otherwise. Older adults may be especially sensitive to its effects.

Pregnancy and breastfeeding: Avoid Rauvolfia vomitoria. Its potent alkaloids and the lack of safety data make it unsafe for the developing baby and possibly for a nursing infant. Do not use it if you are pregnant, trying to become pregnant, or breastfeeding.

Because the strength of products varies and quality control may be poor, always check with a pharmacist or doctor before using any Rauvolfia product.

Side effects

Possible side effects relate to the plant's strong alkaloids and may include:

  • Low blood pressure, dizziness, or fainting
  • Slow heart rate
  • Drowsiness or sedation
  • Stuffy nose
  • Stomach upset, nausea, or increased stomach acid
  • Depression or worsening mood, which can be serious

Larger amounts can cause more serious problems with heart rhythm and blood pressure. Seek medical help if you feel faint, have a very slow or irregular heartbeat, or notice new or worsening depression while using it.

Rauvolfia Vomitoria: Reported Adverse Effects

Documented safety reports on Rauvolfia Vomitoria from the evidence-graded Natural Medicines (TRC Healthcare) database, shown word-for-word from the licensed record.

Orally, Rauvolfia vomitoria is possibly unsafe due to the potential for serious adverse effects from its reserpine and yohimbine constituents.

Serious Adverse Effects (Rare):

Orally: Akathisia, dystonia, hypokinesia, and tremor.

Reports by condition
Angina Cardiovascular

Orally, drinking a beverage made by boiling Rauvolfia vomitoria foliage with bitter orange fruit can reduce levels of high-density lipoprotein (HDL) cholesterol in patients with diabetes. The effect of Rauvolfia vomitoria alone is unclear.

Since Rauvolfia vomitoria contains small amounts of reserpine and yohimbine, theoretically it might also cause some of the adverse effects associated with these constituents. Adverse reactions to reserpine have included angina-like symptoms. At high doses, adverse effects related to yohimbine have included hypertension, tachycardia or palpitations, and myocardial infarction or atrial fibrillation.

Anxiety Psychiatric

In one clinical study, Rauvolfia vomitoria dried root 300-800 mg orally daily for 6 weeks was not associated with reports of depression or thoughts of suicide in patients with psychosis. However, since Rauvolfia vomitoria contains small amounts of reserpine and yohimbine, theoretically it might cause some of the adverse effects associated with these constituents. Orally, low amounts of reserpine may cause nightmares, drowsiness, fatigue, lethargy, and slowed reflexes. In larger amounts, depression may develop. After discontinuation of reserpine, mental depression may persist for several months. Doses of reserpine of greater than 0.5 mg daily appear to increase the risk of these side effects. Orally, yohimbine may increase malaise, fatigue, insomnia, restlessness, agitation, and anxiety.

Asthma Pulmonary/Respiratory

Since Rauvolfia vomitoria contains small amounts of reserpine and yohimbine, theoretically it might cause some of the adverse effects associated with these constituents. Orally, reserpine may cause nasal congestion or bronchospasm. Allergic reactions may also occur; while these events are rare, they may precipitate asthma. Orally, yohimbine may cause bronchospasm, tachypnea, cough, sinusitis, and rhinorrhea. Excessive doses of yohimbine can cause respiratory depression.

Breast cancer Oncologic

Since Rauvolfia vomitoria contains small amounts of reserpine, theoretically it might increase the risk of adverse effects associated with this constituent. Some preliminary research suggested a possible relationship between reserpine products and an increased risk of breast cancer; however, further analysis found that use of reserpine products is not associated with an increased risk of breast cancer.

  1. Lobay D. Rauwolfia in the Treatment of Hypertension. Integr Med (Encinitas). 2015 Jun;14(3):40-6.
Cluster headache Neurologic/CNS

Orally, Rauvolfia vomitoria has been associated with the development of extrapyramidal symptoms in some patients. In one clinical study, 4 out of 10 patients who were taking Rauvolfia vomitoria dried root 300-800 mg daily developed extrapyramidal symptoms, including tremor, akathisia, hypokinesia, and dystonia. Two cases were severe enough to warrant treatment with antiparkinsonian medications.

Since Rauvolfia vomitoria contains small amounts of reserpine and yohimbine, theoretically it might also increase the risk of adverse effects associated with these constituents. Doses of reserpine of greater than 0.5 mg daily appear to increase the risk of side effects. In extremely large amounts, Parkinson-like symptoms, extrapyramidal reactions, and convulsions may occur. Orally, yohimbine has been associated with reports of tremulousness, head twitching, seizures, loss of consciousness, enhanced brain norepinephrine release, decreased energy, dizziness, vertigo, headache, feeling cold, flushing, diaphoresis, and paralysis.

Rauvolfia Vomitoria: Common Questions

What is Rauvolfia Vomitoria used for, and does it work?
People use Rauvolfia Vomitoria for a range of reasons, but according to the Natural Medicines database the current clinical evidence is insufficient to confirm it works for the specific conditions it has been studied for. See the graded list on this page, and talk to your pharmacist or doctor before relying on it for any condition.
Does Rauvolfia Vomitoria interact with prescription medications?
Yes. We list 840 medications with a known interaction with Rauvolfia Vomitoria, including 230 rated major. Use the checker above to see how Rauvolfia Vomitoria interacts with a specific drug.
How are Rauvolfia Vomitoria interactions rated?
Each interaction is graded major, moderate, or minor based on how clinically significant it is and the strength of the evidence behind it. Major interactions are the most serious and are best avoided, or used only under close professional supervision.
Is it safe to take Rauvolfia Vomitoria with my medications?
It depends on the specific medication. Some combinations are fine, while others call for monitoring, timing changes, or should be avoided. Check your exact drug above and confirm with your pharmacist or doctor before starting, stopping, or changing anything.
Where does this Rauvolfia Vomitoria interaction information come from?
Our interaction data is built on the Natural Medicines database — an evidence-graded reference for vitamins, herbs, and supplements — and is reviewed by licensed HelloPharmacist pharmacists, who may add clinical context.
What is Rauvolfia Vomitoria used for?
It has traditionally been used for high blood pressure, anxiety, agitation, and sleep problems, mainly in African folk medicine. Strong scientific proof for these uses as a supplement is limited.
Is Rauvolfia Vomitoria safe to take?
It is not a mild herb. It contains potent alkaloids like reserpine that can dangerously lower blood pressure and cause depression, so it should only be used under medical supervision.
Can I take it during pregnancy or while breastfeeding?
No. You should avoid it during pregnancy and breastfeeding because its powerful alkaloids could harm the baby and safety has not been established.
How is Rauvolfia Vomitoria related to reserpine?
The plant's root naturally contains reserpine, a compound once widely used as a prescription drug for high blood pressure and certain mental health conditions. This is why the herb can have such strong effects.
