There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Squill Overview
Squill is a type of bulbous perennial plant, also known as sea onion or sea squill, that is native to the Mediterranean region and the Black Sea coast. It has been used in traditional medicine and contains a substance known as scillaren A, which is believed to be responsible for its medicinal properties.
Squill has been used for a variety of purposes, including as an expectorant to relieve coughs, as a diuretic to increase urine production and as a 'cardiac tonic', to stimulate the heart and improve circulation. It has also been used topically for hair loss. However, it is important to note that squill contains cardiac glycosides that can be toxic and may cause serious side effects, such as an irregular heartbeat, low blood pressure, and death. It must be used cautiously.
Finasteride Overview
-
Finasteride (Proscar) is used alone or in combination with another medication (doxazosin [Cardura]) to treat benign prostatic hypertrophy (BPH, enlargement of the prostate gland). Finasteride is used to treat symptoms of BPH such as frequent and difficult urination and may reduce the chance of acute urinary retention (sudden inability to urinate). It also may decrease the chance that prostate surgery will be needed. Finasteride (Propecia) is also used to treat male pattern hair loss (gradual thinning of the hair on the scalp, leading to a receding hairline or balding on the top of the head in men.) Finasteride (Propecia) has not been shown to treat thinning hair at the temples and is not used to treat hair loss in women or children. Finasteride is in a class of medications called 5-alpha reductase inhibitors. Finasteride treats BPH by blocking the body's production of a male hormone that causes the prostate to enlarge. Finasteride treats male pattern hair loss by blocking the body's production of a male hormone in the scalp that stops hair growth.
