Carrapichinho (commonly referring to Acanthospermum hispidum) has a longstanding history of traditional use in Brazilian folk medicine and other parts of South America for the treatment of skin conditions, including minor wounds and abrasions. Traditional healers often prepare poultices or infusions from the leaves or aerial parts of the plant to apply topically, aiming to promote healing and prevent infection. The rationale is generally based on the plant's perceived antiseptic and anti-inflammatory properties.

While there are some in vitro and animal studies suggesting that Acanthospermum hispidum possesses anti-inflammatory, antimicrobial, and wound-healing activities, the evidence is limited and not robustly validated in human clinical trials. Most of the support for its use in treating abrasions comes from ethnobotanical literature and documentation of traditional practices, rather than systematic scientific evaluation. The rating of 2 reflects this reliance on traditional use with some preliminary, but not definitive, scientific backing.

In summary, Carrapichinho is primarily used for abrasions based on traditional knowledge, with limited scientific studies providing some support for its bioactivity. However, more rigorous research is needed to confirm its efficacy and safety for this purpose.
