Siberian ginseng (Eleutherococcus senticosus) has been well studied. Researchers found that Siberian ginseng worked as an immune system booster by causing a large “increase in the absolute number of immunocompetent cells, with an especially pronounced effect on T lymphocytes, predominantly of the helper/inducer type, and also on cytotoxic and natural killer cells of healthy volunteers” .
Studies into spearmint (Mentha spicata) found it had potent antimicrobial, anticancer and anti-inflammatory properties . Lemongrass (Cymbopogon citratus) has traditionally been used to alleviate coughs and fever .
A systematic review of 109 randomised controlled trials in 2020, concluded that there was solid scientific evidence that ginger (Zingiber officinale) reduced inflammation in the body  which is in part responsible for some of the symptoms that we feel when we become ill.
