Medicinal plants in skincare
The use of medicinal plants originates from the wide variety of bioactive chemicals. Each plant provides specific skin advantages for various skin types of concerns.

Other plants like Queen Anne’s lace and anacyclus pyrethrum are used to manage autoimmune diseases such as vitiligo. The findings could serve as a foundation for future research into the development of medicinal plants used to treat dermatological illnesses. In addition, the database collected can help biochemists and pharmacologists identify active compounds in medicinal plants used to treat skin-related conditions [2].
