Senna is a plant that has found uses in over-the-counter medications, particularly laxatives or products designed to relieve occasional constipation. Like all plants or plant products, it's possible senna can be a trigger for those who have an allergy. Asthma triggers differ widely among patients. Talk to your doctor if you have asthma and are worried that a product may trigger an attack.
Senna
Senna plants are all part of the same genus, senna, found primarily in tropical and subtropical areas. There are about 250 species of senna, a few of which have practical applications, according to Native Plants Hawaii, a service of the University of Hawaii. People use various kinds of senna plants as food sources, thickening agents, hair treatments and for medicinal purposes.
Asthma Causes
Asthma is a chronic medical condition in which your airways constrict and you're less able to get enough air into your lungs. Allergy symptoms can range from a slight feeling of tightness in the chest, to wheezing and coughing. Some asthma flare-ups or attacks can be so severe they require hospitalization. There appears to be no evidence that senna causes asthma. According to MayoClinic.com, the exact causes of asthma aren't completely understood. While genetic factors are one potential cause, environmental factors also play a role.
Triggers
Asthma attacks or episodes are brought about by specific causes, known as triggers. Triggers differ among asthma patients, though if you're allergic to senna and have asthma, the senna may trigger asthma attacks. If you have a senna allergy, you should limit your exposure to senna and senna-derived products. Consult a physician or allergy specialist if you're not sure whether or not you're allergic to senna.
Considerations
Senna and senna extract are commonly found in numerous stimulant laxatives, sold under various names including Senna, Senekot, Dulcolax and Ex-Lax Gentle Nature. If you're considering taking any of these products and have asthma, ask your doctor first. The senna extract in these products may trigger an asthma attack if you have an allergy, or it may interact with other medications you're taking.
