✵Till the date Oct 10th,2019, there are totally  kinds of common TCM herbs,  kinds of related plant species, kind of mineral, are recorded in this category. These expectorants, herbs for resolving heat-phlegm are briefly introduced separately:
Thallus Laminariae seu Eckloniae(Kelp or Tangle).
Brief Introduction: The herb Thallus Laminariae seu Eckloniae is the dried thallus of sea tangle, Laminaria japonica Aresch., or Ecklonia kurome Okam.(family Laminariaceae), used together with seaweed to eliminate phlegm, soften hard masses and induce diuresis. The herb is commonly known as Thallus Laminariae seu Eckloniae, Kelp or Tangle, Kūn Bù.
✵The herb Thallus Laminariae seu Eckloniae(Kelp or Tangle) is the dried thallus of Laminaria japonica Aresch., or Ecklonia kurome Okam., they are plants of the Laminaria or Saccharina genus, the Laminariaceae(brown algae) family of the Laminariales order.
(1).Laminaria japonica Aresch.: The Laminaria japonica Aresch., is a plant of the Laminariaceae family and Saccharina genus, it is commonly known as "Laminaria japonica Aresch.", "Tangle, or Sea Tangle", or "Hai Dai". Algal body is olive brown, dark brown when dry. Mature leathery strip, generally 2~6 m long, 20~50 cm wide, walking in the middle of the blade with two parallel longitudinal, two grooves and thicker part is "in", the thickness of about 2~5 mm, on both sides of the edge gradually thin, and there are wave creases, leaf blade base cuneate, thick into phase is oblate, a cylindrical or oblate under the short shank, 5~15 cm long, inside the handle and blade are composed of pith, cortex, and the epidermal layer. There are mucus cavities in the outer cortex and secretory cells in the cavities, which can secrete mucus to the surface of the leaf body, forming a gelatinous layer, making the algal body stick and play a protective role. The medulla is composed of many algal filaments, and one end of the cytoplasm is expanded in the shape of a horn tube. The young stage of the algal body leaves smooth, small kelp stage leaves concavo-convex phenomenon. The lower part of the annual algal leaf blade, where the sporangium group is usually seen, is in the form of a nearly round plaque. Biennial algal bodies grow sporangium on almost all leaves. The fixator is composed of a pseudoroot with forked branches. The spores mature in autumn.
(2).Ecklonia kurome Okam.: The Ecklonia kurome Okam., is a plant of the Alariaceae family and Ecklonia genus, some classification system classified it into Lessoniaceae family, it is commonly known as "Ecklonia kurome.", "Tangle, or Sea Tangle", "Kun Bu" or "Hei Kun Bu". Algal body is dark brown, leathery, 30~100 cm high or higher. The lobes are flat, broad, slightly thick in the middle, pinnately lobed from both sides, lobes long or longer, slightly wrinkled, margin generally coarsely serrate. Petiole cauline, cylindrical or slightly flat, 4~12 cm long, 3~8 mm in diameter. In the cortical cells of the algal body, there is a circular arrangement of mucous cavity, which is 1~2 layers. The medullary portion is composed of an indeterminate tube. The sporangium group forms on the surface of the lateral lobes and the central portion of the mature lobes. The fixator consists of a pseudoroot with a bifurcated branch. Sporangium forms in early summer and spores mature in autumn.
