Happy moments always passed so quickly, and soon the sun became hot. Meng Xiyan also felt hungry. She looked at Jiahao and said, "I'm so hungry, shall we go back?" Jiahao She looked at Meng Xiyan and said, "Are you hungry? What do you want to eat in the morning? Can I cook it for you?" Meng Xiyan held Jiahao's hand and said, "Okay, as long as it's made by you, I like everything. Eat." Jiahao looked at such a beautiful and sensible girl, and he was really happy. He held Meng Xiyan's hand and walked slowly down the mountain. As the saying goes, it's easier to go up the mountain than it is to go down the mountain. Although the shoes Meng Xiyan wore today were not high, it was a bit difficult for her to go down the mountain because she didn't often climb mountains. She carefully held Jiahao's hand for fear of falling. . Jiahao looked at the nervous Meng Xiyan. He let go of Meng Xiyan's hand, walked directly in front of Meng Xiyan, bent down, turned to look at Meng Xiyan and said, "Come, let me carry you down the mountain." Meng Xiyan looked at Jiahao , staring at her big, bright eyes and said: "You want to carry me? Can you? This is going down the mountain, aren't you scared?" Jiahao looked at Meng Xiyan and said disapprovingly: "What are you afraid of? "When have I ever been afraid? What does this mean to me? It's my honor to carry you." Meng Xiyan looked at Jiahao and just smiled, with sweetness and emotion in her smile. Meng Xiyan lay gently on Jiahao's back. The faint fragrance of tobacco from Jiahao's body reached Meng Xiyan's nose. She felt that she was still very happy. Listening to Jiahao's rapid breathing, she felt that it was so simple. happiness. Lying gently on Jiahao¡¯s back, her face pressed against Jiahao¡¯s body. Jiahao suddenly felt startled and his heart skipped a beat. He was carrying Meng Xiyan on his back. Meng Xiyan was very light, as if she was almost dead. He felt really happy. Meng Xiyan hugged his neck tightly and said softly: "Jiahao, are you tired? Why don't you put me down? I don't want you to be tired." Jiahao turned to look at Meng Xiyan and said, "Why? Maybe? Carrying you is my happiness? I won't be tired." Meng Xiyan said nothing more and still put her face on Jahao's back happily. I don¡¯t know how long they walked, but Jiahao finally carried Meng Xiyan down the mountain and put Meng Xiyan down. Jiahao straightened his clothes. He looked at Meng Xiyan with a smile and said, "How is it? Am I okay? I just said that I am very strong." Meng Xiyan's face still turned red when he looked at Jiahao, and his forehead was red. Beads of sweat still broke out. Meng Xiyan looked at Jiahao who was sweating from exhaustion. She gently took out a tissue from her pocket, looked at Jiahao and said: "You are still brave. I told you to do it a long time ago." I put it down and you didn¡¯t let it go. Look, you are sweating out from exhaustion. It¡¯s really annoying.¡± Jiahao smiled and moved his head to Meng Xiyan¡¯s side and said, ¡°Then wipe it for me.¡± Meng Xiyan glared. Zhu Jiahao said, "It's really annoying. You did it on purpose. Come on, let me wipe it for you." Meng Xiyan gently helped Jiahao wipe the sweat from his forehead. While wiping, he muttered: "Look at you, I asked you to put me down, but you just didn't let me down. Now you know I'm very heavy, right?" Jiahao looked at Meng Xiyan and gently applied it to Meng Xiyan's ear. Said: "I'm not tired, I'm really happy." Meng Xiyan didn't say anything, and gently hugged Jiahao's neck and said: "Jiahao, you are so kind. Thank you." When Jiahao heard what Meng Xiyan said, His heart felt as if he had eaten honey, and he was so happy that he held Meng Xiyan in his arms. Smelling the fragrance of Meng Xiyan, he gently closed his eyes. The two people hugged each other like this, as if time had disappeared at this moment. It seemed as if everything in front of them disappeared, and what was left was the sweetness and happiness that belonged to the two of them. I don¡¯t know how long it took, but Meng Xiyan let go of Jiahao, faced Jiahao and said, "Okay. Let's go home." Jiahao smiled and nodded, holding Meng Xiyan's hand and walking home. Meng Xiyan¡¯s face was covered with sweat before she had walked a few steps. She was quite excited when she came, but now she feels very tired when she goes back. Her face was covered with sweat, she squatted on the ground and refused to leave. She looked at Jiahao and said, "I can't walk anymore. I don't want to leave." Jiahao looked at Meng Xiyan and said, "How long have you been gone? My big brother "Miss, I will carry you when we go down the mountain." "I won't leave, I just won't leave." Meng Xiyan sat down in a pile of grass. "Look, your clothes are stained with grass juice. Get up quickly." Jiahao said, holding Meng Xiyan's hand. "No? Let's take a break."?Will you stay with me? "Meng Xiyan pouted and said. This girl's trump card is to act coquettishly. As long as she acts coquettishly, the boy will be helpless. Jiahao accompanied Meng Xiyan and sat on the grass. Anyway, since Meng Xiyan didn't care, he didn't care even more. Sitting on the grass , the scent of earth and the freshness of grass reached Jiahao's nose, and he felt a little tired now. 'Jiahao leaned back and lay directly on the grass. Meng Xiyan watched Jiahao lying on the grass. On the bed, she also lay down. The two of them just lay on the grass. The blue sky was filled with white clouds, and sometimes a few birds flew by. Meng Xiyan was intoxicated by this beautiful scenery. "Ah! It hurts. "Meng Xiyan immediately stood up and looked at her legs and said. "What's wrong? What's wrong? What happened? "Jiahao stood up in fright and said. "Jiahao looked at Meng Xiyan's legs and saw that a leech was sucked into her legs. The leech was still on Meng Xiyan's legs. "Meng Xiyan looked at her legs being sucked by a leech. The leech sucked her, and she screamed in fright: ¡°What should I do? Jiahao save me. " Jiahao looked at his frightened face and turned livid, and immediately comforted him: "Don't be afraid, I will save you, it's okay. " Jiahao asked Meng Xiyan to sit down. He patted the leech on Meng Xiyan's leg hard, pulled hard, and took the leech out directly. Meng Xiyan watched the hateful leech come out, and her The tears still flowed down uncontrollably, and he cried and said: "Look, the blood is flowing non-stop. ¡± Dry leech is the general name for leech animals, belonging to the family Hirudidae. It is common in my country as a wide-bodied leech. The body is slightly spindle-shaped, flat and fat, about 6 to 3 cm long. The back is dark green with several yellow stripes in the middle. Vertical stripes, male and female, with suckers at both ends, smaller suckers at the front, and teeth in the mouth. It is widely distributed in my country and is easily seen in swamps, lakes, and rivers. It preys on small animals. Although it stings the skin, it does not suck blood. It is dry early in life. It can be used as medicine. Its shape is similar to that of leeches. It feeds on the blood of humans and animals and can secrete anesthetics. It is not easy to detect when sucking, and the wound often bleeds. Just like Meng Xiyan now, Jiahao looked at Meng Xiyan and said gently. : "Don't be afraid, I'm here and I will help you. " Meng Xiyan hugged Jiahao tightly and said, "Jiahao, I'm scared, I'm really scared. " Jiahao was also bitten by a leech when he was a child. At that time, he still remembered that his grandfather found a kind of grass, that is, airplane grass, which is the best for treating drought leech bites. "Airplane grass is also known as Xiangzelan and Siam grass. , is a perennial herbaceous plant of the Asteraceae family, Asteraceae. The plant is about 1-3 meters high and can reach a maximum of about 7 meters. The rhizome is thick and runs horizontally. The stem is upright, pale in color, and has fine lines on the surface. Striped; branches are thick, often opposite, extending horizontally, at right angles to the main stem, with a few branches alternate and at an acute angle to the main stem; all stems and branches are densely yellow hairy or pubescent perennial herb or shrub. As a sub-shrub, achenes can be spread by the wind through the pappus, and the maturity season coincides with the dry and windy season, so the seeds have a short dormancy period and most or a few flower heads cannot survive in the soil for a long time. The top of the stem or the ends of the branches are arranged in corymb-like or compound corymb-like inflorescences. The inflorescence diameter is usually 3-6 cm, and the peduncle is thick and densely pubescent. The involucre is 1 cm long. cm, 4-5 mm wide, containing about 20 florets; the involucral bracts are 3-4 layers, arranged in an imbricate shape, the outer bracts are oval, 2 mm long, covered with pubescence on the outside, blunt at the top, and gradually inward. Long, middle and inner bracts are oblong, 7-8 mm long, apex acuminate; all bracts have three broad midribs, straw yellow, no glandular spots, white or pink flowers, corolla 5 mm long, tubular. , light yellow, pink stigma. Achenes are narrowly linear, dark brown, 4-5 mm long, 5-ridged, without glandular points, and there are sparse white patches along the edges. Many people don¡¯t like this kind of grass. Everyone thinks It harms a variety of crops and invades pastures. When it grows to 15 centimeters or higher, it will obviously erode indigenous species. It can also release allelopathic substances and has a strong sterilizing effect on different plants, which can inhibit the growth of neighboring plants. It can also make insects refuse to eat. Its leaves are poisonous and contain toxic active compounds called coumarin. Rubbing the skin with the leaves can cause redness, swelling and blistering. Eating the young leaves by mistake can cause dizziness and vomiting. It can also cause irritation in livestock, poultry and fish. Poisoning. This plant is the intermediate host of the leaf spot pathogen. Jiahao knows that this grass has high medicinal value, slightly pungent taste, and is slightly toxic. Its main functions are: dispersing blood stasis, reducing swelling, detoxifying, and stopping bleeding. Swelling and pain; sores and venom; paddy field dermatitis; traumatic bleeding; continuous bleeding after being bitten by drought locust. This species is a poisonous plant included in the Chinese Plant Atlas Database. Its leaves are poisonous and can be treated by rubbing the leaves on the skin. Causes redness, swelling and blistering, accidentally eating the young leaves can cause dizziness and vomiting, and can also poison fish and kill insects. To treat drought, if locust bites cause bleeding, rub the fresh leaves into the wound and apply it to the wound. The decoction of leaves and stems has an excitatory effect on the isolated guinea pig ileum, the water extract (with alcohol added to remove the precipitate) has a weak effect, and the decoction has an inhibitory effect on the isolated rabbit duodenum. Both of them had no obvious effect on isolated rabbit uterus. Both were very toxic when injected intraperitoneally into mice. Jiahao found the airplane grass, crushed it gently and put it on Meng Xiyan¡¯s lap.
