What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

Tylophora: Uses, Safety & Side Effects

The bottom line

Tylophora is a climbing plant used in traditional Indian (Ayurvedic) medicine, most often for asthma and breathing problems. Some older, small studies suggested possible benefit for asthma, but the evidence is weak and limited, and the plant can cause notable side effects. Talk to your pharmacist or doctor before trying it, and never use it to replace proven asthma treatments.

Overview

Tylophora is a climbing or twining plant native to India and parts of Southeast Asia. It has long been used in traditional Indian (Ayurvedic) medicine, where it is sometimes called "Indian ipecac" because, like ipecac, large amounts can cause vomiting.

The leaves and roots are the parts most often used. Traditionally, people chewed the leaves or made preparations from them to help with asthma, allergies, and other breathing problems. Today it is sold in some supplement products as capsules, powders, or tinctures.

How it works

Tylophora contains compounds called alkaloids, with tylophorine being the most studied. In laboratory and animal research, these alkaloids have shown anti-inflammatory and immune-modulating effects, which is one reason the plant was studied for asthma and allergies.

Researchers have also looked at tylophorine in cell studies for possible effects on inflammation and abnormal cell growth. It is important to understand that these are early, mostly test-tube and animal findings. They do not confirm that Tylophora produces meaningful benefits or works safely in humans.

Insufficient Reliable Evidence To Rate Asthma
Rating & evidence shown verbatim from Natural Medicines

There is contradictory evidence about the effectiveness of Tylophora for asthma. Preliminary clinical research suggests that placing Tylophora extract containing total alkaloids 0.5 mg in 0.5 grams glucose on the tongue and then swallowing, followed by a 1-2 hour bed rest without food daily for 6 days, or taking Tylophora extract 40 mg daily for 6 days, appears to improve symptoms of asthma. At the end of the first week, up to 57% of patients in the Tylophora groups were improved compared with 23.5% to 31.6% of patients in the placebo groups. This improvement in the Tylophora group continued to last until at least the end of an 8-week follow-up period. Similarly, taking a single Tylophora leaf daily for 6 days increases the number of patients reporting moderate to complete relief of symptoms compared to taking a spinach leaf. Approximately 11% to 28% of patients treated with spinach leaf reported improvement compared to 50% to 62% of patients treated with Tylophora leaf. Taking Tylophora leaf powder 350 mg daily for 7 days also appears to improve asthmatic symptoms when compared to placebo.

Safety & precautions

Tylophora is not well studied for long-term safety in people. It can cause stomach upset and vomiting, especially at higher doses, which is part of why it was traditionally compared to ipecac.

People with asthma should be especially careful: relying on an unproven herb instead of prescribed inhalers or other medicines can be dangerous during an asthma attack. Anyone with a chronic medical condition should check with a pharmacist or doctor first.

Pregnancy and breastfeeding: There is not enough safety information, and there are traditional concerns about its use in pregnancy. To be safe, avoid Tylophora if you are pregnant, trying to become pregnant, or breastfeeding.

Side effects

The most commonly reported side effects are nausea, vomiting, mouth or throat soreness, loss of appetite, and altered taste. These effects appear more often at higher doses.

Some people may have allergic reactions to plant products. Stop using it and seek medical care if you notice rash, swelling, difficulty breathing, or other signs of a serious reaction. Because the plant's safety is not well established, it is wise to use caution and report any unusual symptoms to your healthcare provider.

Dosing

There is no well-established or standardized dose for Tylophora. Older studies used small amounts of dried leaf for short periods, but these doses have not been confirmed as safe or effective.

If you choose to use a product, follow the directions on the label and do not exceed them. Because the strength of herbal products can vary a lot between brands, and because Tylophora can cause vomiting at higher amounts, it is best to talk with a pharmacist or doctor before starting it.
