Over the past few decades, an increasing number of studies have investigated whether or not there is an increase in atmospheric CO2 will alter the amount and concentration of various health-promoting substances found in medicinal plants or “health foods”.
For example, AbdElgawad .’s team et al. (2021) recently examined the “nutritional values, phytochemicals (i.e., pigments, phenols, flavonoids, vitamins, mineral profiles and essential oil yield) and antioxidant activities of whole sprouts) caraway and mature trees.”
Caraway tree (Carum carvi) is an important medicinal plant. They are grown globally and are used to treat a number of ailments, including diarrhea, asthma, cholera, and hypertension. Also, AbdElgawad et al. notes that caraway berries “have been prescribed in herbal mixtures as a remedy for digestive, digestive, and lactation disorders,” and they are also used as “antiallergic, antibacterial, anthelmintic, antifungal, bronchodilator and cholinergic agents.”
Based on the many traditional uses of the caraway plant, it is not surprising that many strategies have been adopted to improve its growth and medicinal properties, including CO2 enrich. Because of the increased levels of CO in the atmosphere2 representative promote photosynthesis of plants and the production of secondary compounds, the twelve-member research team predicted that elevated CO2 will also enhance the medicinal properties of caraway.
To discover their hypothesis, AbdElgawad et al. grow caraway in controlled environmental chambers under ambient (400 ppm) or high (620 ppm) CO2 conditions, harvest the plants after 9 or 45 days (seedlings or mature plants, respectively). They then performed a series of analyzes designed to quantify CO2-Differences in phytochemical properties.
And what did those analyzes reveal?
First, as shown in Figure 1, a 220 ppm increase in atmospheric CO2 improved photosynthesis, chlorophyll content, fresh weight and dry weight of sprouts by 66%, 50%, 64% and 120%, respectively. Similarly, significant CO2-improvements in these four parameters were also observed in mature plants (40%, 44%, 48% and 29% respectively for photosynthesis, chlorophyll content, fresh weight and live weight). dried).
Abd Elgawad et al., further reported that CO is elevated2 significantly increases the production of carbohydrates, proteins, fats and crude fiber in caraway, as well as amino and organic acids, regardless of the growth stage (germination or mature plant). Higher CO2 also enhances phytomineral, vitamin and phenol content, as well as antioxidant and antimicrobial activities.
Commenting on some of these findings, the authors explicitly state: “overall, elevated CO2 induce changes in the phytochemical content of caraway plants, especially at the germination stage and thereby, improve their nutritional and health-promoting properties. ” And they are not alone in this overall assessment. Many other studies performed on a wide range of other plant species have reported CO2– enhance substances known to be effective in fighting cancer, diseases and many other pathologies.
