Serpina by Himalaya Herbal Healthcare is an herbal, non-prescription supplement used to alleviate anxiety and hypertension. Serpina is available as orally consumable tablets sold over the counter.
Serpina tablets contain Indian snakeroot (scientifically known as Rauvolfia serpentine) as the single active ingredient. Each 250 mg Serpina tablet contains 4 mg of Indian snakeroot extract.
Indian snakeroot was traditionally used to treat venomous snake bites, but came to be known as an all-purpose remedy to treat a variety of conditions including hypertension, fever, epilepsy, dysentery, cholera, intestinal problems, pimples, boils, uterine contractions, corneal opacity, insomnia, nervousness, hypochondria, menstrual pain and even to ease the pain of childbirth.
The root bark of Indian snakeroot is rich in alkaloids, one of which is chemically similar to the rauwolfia alkaloid reserpine. Reserpine is a medically prescribed drug that relieves hypertension and psychotic symptoms. Prescription reserpine works by reducing the release of neurotransmitters in the brain such as serotonin and norepinephrine, which then helps to lower mild to moderate high blood pressure, schizophrenia and agitation in patients with mental health issues.
Manufacturers of Serpina claim that the herb depletes peripheral catecholamine (noradrenaline) stores, which relaxes blood vessels resulting in lowered blood pressure. High blood pressure left untreated can lead to heart attacks, strokes and kidney problems. Serpina is also said to decrease adrenergic tone to control anxiety.
