Plantago Major

What is it? Its traditional use?

Plantago major is a flowering plant which is native to Eurasia and now has an almost worldwide distribution. It has been used in folk medicine for centuries, and its medicinal benefits have long been acknowledged (Samuelsen, 2000). It is however only in the last twenty years or so, that scientific research has began to quantify and study this.

The plant is made up of phytochemicals including flavonoids and alkaloids, along with fatty acids, polysaccharides and vitamins; each of which are thought to be key elements in its therapeutic effect. In folk medicine it has been used both topically and ingested to treat a range of ailments. The plant leaves have been traditionally used to promote the healing of wounds, burns and insect bites. Additionally, it has also been used to treat respiratory and digestive diseases. It is also thought to have anti-cancer properties, as well as being used for pain relief and to treat infection (Samuelsen, 2000)

What the research says

1. In Vitro experiments

Some in vitro experiments have isolated phytochemicals from the plant to investigate their potential individual roles. In one study the flavonoid aucubin, extracted from plantago m. was found to be a highly active compound. It demonstrated both anti-inflammatory and antioxidant effects (Zeng, 2020).

Another study found that aucubin extracted from the plant had anti-microbial effects. Findings showed it was effective against numerous strains of both gram positive and negative bacteria strains(Özkan et al., 2012; Sharifa et al., 2008; Abd Razik et al., 2012). Aucubin taken from the plant is likely an effective anti-fungal; one study found it effective again biofilm production of the common strain Candida albicans (Shirley et al, 2015).

Research also supports that the plant has anti-viral properties- one study using a hot water extract (Chiang et al, 2002) and another using phytochemicals extracted from it (Chiang et al, 2003). It was found that caffeic acid and chlorogenic acid showed strong activity against a broad spectrum of viruses (Chiang et al, 2003).

2. Clinical Studies- Topical Use

Application of Plantago major topically has been shown to accelerate the healing of wounds, burns and ulcers. The healing of burns on rats were significantly improved with use of a 50% Plantago major topical ointment. It has been suggested that it could be a suitable replacement for silver sulfadiazine, a commonly used product for patients with skin infections arising from burns (Amini, 2010). A randomised blind clinical trial found that topical treatment of Plantago significantly improved the healing of pressure ulcers; 96% compared to 73% in the control group recovered after 2 weeks (Ghiasian et. al 2021). Another key finding in this study showed no side effects from using this treatment. Similarly, a clinical study testing topical gel resulted in a significant reduction in wound sizes of diabetic foot ulcers and pressure ulcers, compared to control groups (Ghanadian et. al, 2022). Studies also indicate the plant extract acts an anti-inflammatory and analgesic (Núñez Guillén et al., 1997)

It is not surprising that this plant has been used in folk medicine for centuries, given the wealth of emerging research to support its medicinal properties. Research has shown no side effects of its use, proven its antimicrobial and anti-inflammatory properties, and also its ability to accelerate wound healing in human and animal studies. It therefore shows great promise as a holistic complementary treatment to wound healing.
