What side effects this plant can have?
This plant can cause an unpleasant astringent taste in the mouth due to its high concentration of tannins. Consuming the leaves or stems often leads to a drying sensation on the tongue and mucous membranes. This puckering effect is a common physiological reaction to the chemical compounds found within the plant's tissues. Some individuals may also experience mild gastrointestinal discomfort if excessive amounts are ingested. Careful observation is necessary when interacting with this species to avoid these sensory and digestive reactions.
According to a study published by "Food chemistry: X", the bitter and astringent taste and miscellaneous smell of Ampelopsis grossedentata prevent its further development. Sensory evaluation showed that a yellowing process of 6-12 h significantly reduced bitterness and astringency. This process was related to the down-regulation of anthocyanins by 54.83-97.38%, the hydrolysis of gallated catechins by 34.80-47.81%, and flavonol glycosides by 18.56-44.96%. These changes led to the accumulation of d-glucose by 33.68-78.04% and gallic acid by 220.96-252.09%. Additionally, the total volatile metabolite content increased by 23.88-25.44% with key compounds like geraniol increasing by 239.32-275.21%.
The main side effects this plant can have are shown in the list below.
