Rhubarb: what it is, what it is for and how to use it

Rhubarb is an edible plant that has also been used for medicinal purposes, as it has a powerful stimulating and digestive effect, used mainly in the treatment of constipation, due to its rich senoside composition, which provide a laxative effect.

This plant has an acidic and slightly sweet taste, and is usually consumed cooked or as an ingredient in some culinary preparations. The part of rhubarb used for consumption is the stem, because the leaves can cause severe poisoning by containing oxalic acid.

Rhubarb main benefits

The consumption of rhubarb can provide several health benefits, such as:

  • Improve eye health, as it contains lutein, an antioxidant that protects the eye macula
  • Prevent cardiovascular diseases, for containing fibers that reduce the absorption of cholesterol in the intestine and antioxidants that prevent atherosclerosis
  • Help regulate blood pressure and improve blood circulation, as it has antioxidants that provide an anti-inflammatory effect. In addition, it is rich in potassium, a mineral that helps to relax blood vessels, favoring the passage of blood through arteries
  • Improve skin health and prevent pimples, being rich in vitamin A;
    Contribute to cancer prevention, by containing antioxidants that prevent cell damage caused by the formation of free radicals;
    Promote weight loss due to low calorie content
  • Strengthen the immune system, as it is rich in selenium and vitamin C;
    Relieve symptoms of menopause, due to the presence of phytosterols, which help to reduce hot flashes (sudden heat)
  • Maintain brain health, because in addition to containing antioxidants, it also contains selenium and choline that help improve memory and prevent neurodegenerative diseases, such as Alzheimer’s or senile dementia.
  • It is important to mention that these benefits are found in the rhubarb stem, as its leaves are rich in oxalic acid, a substance that can cause serious health problems, because when consumed in large quantities, it can be nephrotoxic and have a corrosive action. Its lethal dose is between 10 and 25 g, depending on the person’s age.

How to use

Rhubarb can be eaten raw, cooked, in the form of tea or added to recipes like cakes and pastries. Consuming it cooked helps to reduce the oxalic acid content by about 30 to 87%.

If the rhubarb is placed in a very cold place, such as the freezer, oxalic acid can migrate from the leaves to the stem, which can cause problems for those who consume it. Thus, it is recommended that rhubarb be stored at room temperature or under moderate refrigeration.
