Imperforate St John's-wort
Hypericum maculatum
Hypericum maculatum, a member of the St. John's wort family, is found in various regions but has not been traditionally used for medicinal purposes. The plant's traditional uses remain undocumented across different cultures and practices. Scientific evidence on Hypericum maculatum is limited, with most studies focusing on its ecological traits rather than medicinal applications. Research indicates that populations near the range edge or in heterogeneous environments exhibit greater phenotypic plasticity, while seedling emergence can be constrained by competition from neighboring vegetation in sub-alpine settings. Additionally, this species shows moderate copper accumulation under tree canopy and responds to UV radiation by increasing epidermal UV-screening; however, its response to reduced water availability is less clear. Safety concerns for Hypericum maculatum are minimal, with no major issues recorded. There have been no reports of significant drug interactions associated with the plant.

What the science says
- Populations of Hypericum species closer to the range edge or from more heterogeneous environments tended to exhibit greater phenotypic plasticity in certain traits.
- Seedling emergence was limited by competition from neighboring vegetation in sub-alpine species at alpine locations.
- Hypericum maculatum accumulated copper at levels above permissible values in uncontaminated soil under tree canopy.
- UV radiation increased epidermal UV-screening but did not significantly alleviate the negative effects of reduced water availability on gas exchange and morphological parameters in both grass and forb species.
