Allium tuberosum Rottl., commonly known as Chinese chive or garlic chive, has a history of use in Traditional Chinese Medicine (TCM) and other East Asian medicinal systems. In these traditions, it is believed to have warming properties and is sometimes used to relieve muscle cramps and spasms, particularly of the lower limbs or abdomen. The seeds (Jiǔ Cài Zǐ) and the fresh leaves are both utilized in herbal formulations, often combined with other herbs thought to invigorate qi and relieve pain.

However, direct scientific evidence supporting the efficacy of Allium tuberosum for treating cramps or spasms is extremely limited. There are a few in vitro and animal studies suggesting that extracts from the plant may have mild antispasmodic or smooth muscle relaxant effects, but these studies are preliminary and do not provide robust clinical data. The majority of references to its use for cramps and spasms are based on traditional usage, not on modern clinical trials or pharmacological validation.

In summary, the use of Allium tuberosum for cramps and spasms is primarily justified by traditional practices, with little to no strong scientific evidence to confirm its effectiveness for these conditions.
