Ignatius Bean Overview

Ignatius Bean Strychnos ignatii is a climbing shrub native to the Philippines and Southeast Asia, with its seed known as the Ignatius bean. This bean contains toxic compounds like strychnine and brucine. Historically, it was used in traditional medicine for its stimulating properties and to treat paralysis and digestive issues. However, due to its toxicity, it's considered unsafe. Ingesting 30-50 mg of the bean (containing about 5 mg of strychnine) can cause restlessness, anxiety, heightened senses, increased reflexes, balance issues, stiff and painful neck and back muscles, twitching, spasms of the jaw and neck muscles, kidney failure with urine discoloration, muscle tissue breakdown, severe tension, and difficulty breathing due to muscle spasms. Because of these effects, extreme caution should be exercised, and medical guidance is strongly advised before using Ignatius bean.

Riociguat Overview

  • Riociguat is used to treat pulmonary arterial hypertension (PAH; high blood pressure in the vessels that carry blood to the lungs). Riociguat is also used to treat chronic thromboembolic pulmonary hypertension (CTEPH; high blood pressure in the lung arteries caused by blood clots that narrow or block blood flow) in adults who cannot have surgery or for those treated with surgery who continue to have high lung blood pressure levels after surgery. Riociguat may improve the ability to exercise in people with PAH and CTEPH and may slow the worsening of symptoms in people with PAH. Riociguat is in a class of medications called soluble guanylate cyclase (sGC) stimulators. It works by relaxing the blood vessels in the lungs to allow blood to flow easily.
