Alpine Ragwort Overview

Alpine Ragwort Senecio nemorensis, commonly known as wood ragwort, alpine ragwort or mountain groundsel, is a perennial herbaceous plant belonging to the Asteraceae family. It is native to Europe and Asia. This species is characterized by its erect stems, which can grow up to 50 centimeters tall, and its bright yellow composite flowers that bloom from late spring to early summer. Wood ragwort is known for its toxicity, containing pyrrolizidine alkaloids that can be harmful to livestock and humans if ingested. PAs, particularly unsaturated ones like retrorsine and senecionine, are the most hepatotoxic, causing liver damage through mechanisms involving oxidative stress. Those looking to take dietary supplements containing Senecio nemorensis should be advised against using preparations that are not certified and labeled as hepatotoxic PA-free.

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).
