Jixuecao was first recorded in the Shennong bencaojing. The variety of plant referred to is undefined because of a lack of detailed description in the medical books of the Han and Tang dynasties. From the Song dynasty to the Republican period Jixuecao refers to Glechoma longituba (Nakai) Kupr. The name was also recorded as Jinqiancao instead of Jixuecao in the Bencao gangmu shiyi from the Qing dynasty to the Republican period, though it refers to the same plant. In recent times, Jixuecao has evolved to refer to Centella asiatica (L.) Urb, Jinqiancao now refers to Lysimachia christinae Hance, while G. longituba (Nakai) Kupr. is now called Lianqiancao. It is thus determined that G. longituba (Nakai) Kupr. alone is unequivocally the original plant referred to as Jixuecao, and has the longest medicinal history.
积雪草始载于《神农本草经》。汉唐时期本草形态描述过于简单，导致药用基原不明。宋代至民国积雪草基原明确，为唇形科植物活血丹Glechoma longituba (Nakai) Kupr.。清代《本草纲目拾遗》以"金钱草"之名替代"积雪草"进行收载，民国时期沿用"金钱草"之名，但基原仍为唇形科植物活血丹G.longituba (Nakai) Kupr.。近代积雪草基原变成伞形科植物积雪草Centella asiatica (L.) Urb.，金钱草基原变成报春花科植物过路黄Lysimachia christinae Hance，而历代本草所用积雪草和金钱草基原活血丹G.longituba (Nakai) Kupr.则变成中药"连钱草"。唇形科植物活血丹G.longituba (Nakai) Kupr.基原明确，药用历史悠久，符合历代本草对积雪草的记述。.
