What is Rhubarb?
Rhubarb, a part of the Polygonaceae family of plants, is a unique looking plant with a very interesting history. Scientifically, it is an herbaceous perennial with leaves growing off the top of a thick rhizome.
Although widely considered as a vegetable, in America, it is treated as a fruit, in culinary practices. The leaf stalks are actually the only parts of the plant consumed, sometimes as a dessert or an ingredient in sweet dishes.
It is cultivated throughout the year in different parts of the world and widely available in any season. It possibly grows in greenhouses, resulting in “hothouse” rhubarb, which is sweeter and deeper red in color, while the traditional variety is grown outside. One of the main reasons why people cultivate and eat rhubarb is for its astoundingvalue. It is packed with minerals, vitamins. organic compounds, and other nutrients that make it ideal for keeping our bodies healthy.
What does Rhubarb Taste like?
The taste of rhubarb is somewhat similar to that of green apples, which is to say that it is tart. Usually, people add sugar to make it sweeter and then bake or cook it. Also, raw rhubarbs have a sour and acidic taste.
It is also often paired with strawberries because of the lovely pair of tart and sweet that they make. Some people also often compare the taste of it with celery.
Is Rhubarb Poisonous?
Interestingly enough, the stalks are the only things eaten from this plant. The triangular leaves are extremely high in oxalic acid, which can cause severe illnesses in people if consumed, resulting in the common belief that rhubarb is poisonous. If the plant is subject to extreme cold, the dangerous acid can migrate into the stalk, so be sure to store it in a warm or temperate space, just like the climate where it normally grows.

Health Benefits of Rhubarb
Let’s see how the nutrients add up to the long list of health benefits that rhubarb imparts!
Rhubarb is one of the vegetables with low calories and it is often recommended for people who are struggling to lose weight but still want to remain healthy. 100 grams of the plant contains 21 calories, so feel free to load up on it without packing on any pounds. Additionally, the fiber helps you feel full faster which may further reduce total caloric intake and promote weight loss. A study published in the Journal of Zhejiang University of Traditional Chinese Medicine showed that compounds in rhubarb may help gastric emptying which may promote weight loss.
The fiber present in rhubarb stalks is helpful in lowering cholesterol levels. In an animal study published in the Nutrition Research journal, it was found that rhubarb can help in regulating levels even if you eat a moderately cholesterol-enriched diet.
Aids in Digestion
The high amount of dietary fiber found in rhubarb may guarantee a healthy digestive system by bulking up the stool, making sure that bowel movements are smooth and regular. Also, it has traditionally been used as a cure for constipation but was only recently discovered why. By easing and other digestive issues, rhubarb may help prevent a wide range of more serious disorders, which include bloating and cramping.
According to a study published in the Brain Research Bulletin journal, rhubarb glucoside compound rhaponticin protects the body against Alzheimer’s. Furthermore, in vitro results show the positive effect of rhaponticin in preventing the harmful effects of amyloid-beta that are crucial in the formation of senile plaques. Based on this study, it is suggested that rhaponticin could possibly be developed as agents for the management of Alzheimer’s disease.
Improves Bone Health
Rhubarb is a good source of vitamin K that is associated with promoting osteotropic activity, meaning that it stimulates bone growth and repair. Combined with the rich amount of calcium and other minerals found in rhubarb, the vegetable as a whole is a major player in bone protection.
According to the researchers from the National University of Singapore, anthraquinones from rhubarb possess anti-cancer properties and could have therapeutic potential. It is a good source of beta-carotene, which the body converts to vitamin A, protecting the skin and eyes from the effects of free radicals. Other compounds like lutein and zeaxanthin which also act in a similar way to vitamin A, as powerful antioxidants and cancer-preventing agents. A decent amount of antioxidants in your diet can help avoid premature aging, cataracts, macular degeneration, and wrinkles.

The trace amounts of copper and iron found in rhubarb are essential for the production of new red blood cells, necessary to maintain the total RBC count in the body. Maintaining adequate healthy red blood cells is essential for oxygenation of the body, thereby ensuring optimum function. Furthermore, according to an animal study in the Chinese Medicine journal, rhubarb not only promotes blood circulation but also processes the effect of hemostasis.
Helps Manage Diabetes
Rhubarb is low in carbohydrates and can be used in preparations that are diabetes-friendly. A 2018 study suggests the use of the essential oil extract of the rhubarb stem as an additional treatment, owing to its positive effect on fasting blood glucose levels. Another paper published in the Systems Microbiology journal suggests that rhubarb extracts can exert a effect as well as improve gut microbiota.
Rhubarb contains beta-carotene, vitamin C and lutein, which are compounds that are beneficial for vision and protective to the retina.
Relieves Perimenopause Symptoms
Rhubarb being rich in vitamin A, an antioxidant, may help fight off free radicals and delay the signs of aging including wrinkles and fine lines. It also acts as an anti-antibacterial agent that may help prevent skin infections and acne.and
