Tragacanth Overview
Tragacanth is a natural gum that is derived from the sap of several species of Middle Eastern and Mediterranean plants, including Astragalus gummifer and Astragalus tragacanthus. In traditional medicine, this gum tragacanth has been used to treat a variety of conditions, including gastrointestinal disorders and sore throat. It is believed to work by forming a protective barrier on the mucous membranes of the digestive and respiratory tracts, which can help to soothe irritation and reduce inflammation.
Tadalafil Overview
-
Tadalafil (Cialis) is used to treat erectile dysfunction (ED, impotence; inability to get or keep an erection), and the symptoms of benign prostatic hyperplasia (BPH; an enlarged prostate) which include difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying), painful urination, and urinary frequency and urgency in adult men. Tadalafil (Adcirca) is used to improve the ability to exercise in people with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Tadalafil is in a class of medications called phosphodiesterase (PDE) inhibitors. It works to treat erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Tadalafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow more easily.
-
If you are taking tadalafil to treat erectile dysfunction, you should know that it does not cure erectile dysfunction or increase sexual desire. Tadalafil does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV).
