Persicaria Maculosa it is also referred to as Polygonum Persicaria.
This is not medical advice and should not be taken as such. If in doubt don’t. Make sure you know a plant before you use it. I have eaten Lady’s Thumb, it does not have much taste but a similar plant that can easily be mistaken for lady’s thumb has a peppery taste. I do not think it has much nutritional value but some studies have shown it reduces symptoms of herpes.
Lady’s Thumb does contain a potassium channel blocker. This means it could slow the heart rate down.
This also gives it cancer fighting properties.
It has antifungal properties.
The polygonum species are all high in antioxidants.
They inhibit xanthine oxidase which would prevent excess reactive oxygen species.
