Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Parasiticide  Parasiticide  Vulnerary

Larkspur formerly had a reputation for its ability to consolidate and heal wounds[244], whilst the juice from the leaves is considered to be a remedy for piles and an infusion of the flowers and leaves has been used as a remedy for colicky children[244]. However, the whole plant is very poisonous and it should not be used internally without the guidance of an expert. Externally, it can be used as a parasiticide[207]. A tincture of the seed is applied externally to kill lice in the hair[240].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

The seed is insecticidal[240]. A tincture made from the seed is said to be effective against hair nits[244]. There is uncertainty as to whether the insecticidal effect is due to the oil or alkaloids in the seed[240]. The seed contains 39% of a fixed oil, though the report does not say if this is ever exploited[240].
