Buckhorn Plantain (Plantago lanceolata) has a long history of traditional use in herbal medicine, particularly in European and Asian folk remedies. Its leaves are known for their anti-inflammatory, astringent, and wound-healing properties. Traditionally, poultices or infusions made from Plantain species have been applied topically to aid in the healing of minor wounds, cuts, and skin inflammations, which has led to their use in conditions like anal fissures and fistulas. The mucilaginous compounds in the plant are believed to soothe irritated tissues and promote healing, while the astringent action may help reduce local bleeding and inflammation.

However, when it comes to scientific validation, there is only limited in vitro and animal research suggesting that Plantago species possess anti-inflammatory and wound-healing properties. No robust clinical studies or high-quality human trials specifically evaluate the effectiveness of Buckhorn Plantain for anal fissures or fistulas. Most references to its use for these conditions are found in ethnobotanical surveys or traditional herbal handbooks rather than scientific literature. Therefore, the evidence supporting its use is rated as 2 out of 5, reflecting that it is primarily based on tradition with minimal scientific substantiation.

In summary, while Buckhorn Plantain is cited in traditional medicine for supporting wound healing in anorectal disorders, rigorous clinical evidence is lacking, and its use for anal fissures or fistulas remains largely supported by historical, not scientific, sources.
