Butterbur for Allergies

Butterbur

Butterbur, or Petasites hybridus, is a type of marsh plant that’s long been used
for medicinal purposes. It grows throughout Europe and in certain parts of Asia
and North America. It gets its name from its large leaves that were used to
wrap butter to keep it fresh in warm weather.

All parts of the butterbur plant have also been
used to treat a variety of health problems. It’s still used to treat headaches,
especially migraines.

Researchers say butterbur is effective in reducing the intensity and
frequency of migraines.

Research on butterbur in treating allergies

It is estimated that 30 percent of American
adults and 40 percent of children are affected by allergies. Because of its reputation for treating a number or illnesses,
butterbur is now being studied as a possible treatment for allergies.

So far findings suggest that the plant may be
an effective treatment for nasal allergies. Butterbur would be administered as
an oil extract or in pill form.

One study found that butterbur could suppress allergic reactions in rats.
In a human study, people with allergies that were given butterbur tablets for a
week showed significant improvement of their allergy symptoms. After five days
of treatment, the participants’ bodies contained smaller amounts of the allergy-producing
substances leukotriene and histamines.

How does butterbur work?

When your body comes into contact with an
allergen, it releases the inflammatory chemical leukotriene. Leukotriene is what’s
responsible for triggering an allergic reaction in your body.

Leukotriene (LT) inhibitors block leukotriene
and prevent or relieve an allergic reaction. Butterbur seems to act as an LT
receptor inhibitor, much like the drug Singulair (montelukast) used to treat nasal allergies.

However, researchers haven’t yet found that
it is useful in treating asthma or skin allergies.

What are the risks of using butterbur?

Unprocessed butterbur
contains chemicals called pyrrolizidine alkaloids (PAs). PAs can cause serious
liver damage and other illnesses.

However, the National
Institutes of Health (NIH) reports
that PA-free butterbur products are safe, effective, and don’t cause side
effects in most people. They should be taken by mouth in the recommended doses
for 12 to 16 weeks. However, it is not known if using butterbur for a long
period of time could cause problems.

Most people tolerate
butterbur well, but it may cause side effects in some people. Side effects most
often affect those who are allergic to plants. Because butterbur is part of the
daisy family, you should avoid using it if you are allergic to plants in that
family. Side effects may include:

  • allergic
    reactions
  • belching
  • headaches
  • itchy eyes
  • digestive
    problems
  • fatigue
  • sleepiness

You should always talk to
your doctor before starting an alternative allergy treatment. Because butterbur
could cause allergic reactions, it should only be given to children under a
doctor’s supervision. It’s also important that if you use butterbur products you
make sure that they are processed and labeled as PA-free.
