The days passed like this, and spring came.

Spring is the time when diseases are common, and it is easy to get sick in both spring and winter.

Spring is a time of rejuvenation, and there are some diseases that are also on the horizon. Therefore, Su Lan is also seriously studying what kind of drugs need to be developed during this time period.

Until one day, there was a child in a family with a stomachache, and then invited Su Jimin to see it, although he found that there was no insecticide medicine in this era.

Most of the children in this era would drink raw water, or they would get sick from their mouths when they were not paying attention.

The awareness of hygiene in this era is not good, and people nowadays are not very hygienic, so there are still worms in the stomach, such as roundworms or other insects.

When Su Lan was young in her previous life, she also had worms in her stomach, and she also took medicine to beat the worms out.

Su Lan still remembers it vividly, after she took the insect medicine when she was a child, when she pooped, the appearance of a roundworm in the poop was really scary.

Especially those bugs that come out of the poop are like earthworms, and they are really disgusting to look at.

The child with a stomachache was then confirmed by Su Jimin's diagnosis that the child did have roundworms in his stomach.

Su Jimin prescribed some medicine, and the child's parents followed him home to grab the medicine, and then took it back to cook it for the child to drink.

Of course, the parents of the children also know very well that of course there will be worms in the stomach of children, after all, children are not very hygienic, and they will always get some minor diseases if they eat uncleanly.

They themselves are from the past, and of course they know that this is inevitable, so they don't make much fuss.

The insecticide caught by the Su family's father and son is still very good, and the effect is really good, and the roundworms in the children's stomachs can be shot out soon.

It's just that after knowing that the roundworms in the stomach of the children will occur frequently in this season, they will come out and talk about resident sports, and the deworming drugs will be mass-produced.

Just like the previous frostbite cream, cold medicine and antipyretic, it is mass-produced and made into a finished medicine, and then sold.

In this way, the anthelmintic medicine can also become an over-the-counter medicine, and you can buy it yourself and give it to your children to take worms.

"Lan'er, you are so smart, you can even think of such a way, why didn't I think of it?" Su Jimin saw that his daughter had tossed out the mass-produced insecticide again, and praised Su Lan very happily.

"Dad, you're just too busy, so I didn't think about it for a while. And I'm idle, I have a lot of time to think, so that's why I come up with it. Su Lan smiled, not modestly taking all the credit on herself.

"Our family Lan'er is really very smart and very benevolent." Su Jimin said very proudly.

The people of the Su family soon put the deworming medicine on the agenda, and once again made a concerted effort to make the deworming medicine, and then mass-produced and sold it for the children to be insected.

After the Su family's deworming medicine was made, everyone felt really good, because every year they would have the experience of the children's stomach ache being tossed by the insects, so everyone was very concerned about the children at home.

Of course, what is even more frightening is that there are worms in the stomach, which is too frightening, so after having the insecticide and the worming, it also makes everyone feel a lot more at ease.

Later, both adults and children took the insecticide, just to get rid of the worms in their stomachs.

What I didn't expect was that not only children had worms in their stomachs, but also adults in their stomachs who had not taken the Su family's anti-worming medicine, and they had some bugs in their stomachs.

After everyone bought the medicine and knocked out the parasites in their stomachs, they were much more relieved and respected the Su family's medicines even more.

This time, the Su family still wants to give deworming medicine to the military, and they cooperate with the military to make anthelmintic medicines, cold medicines and fever reducers, as well as frostbite medicines.

And Pei Yuan Dan Qi Replenishing Pill, Blood Replenishing Pill see bill of lading, etc., these drugs that have the functions of maintaining and conditioning the human body, consolidating the foundation of Peiyuan, and strengthening the body are all handed over to the state.

The Su family is not short of this money, and if they give the prescription of the latter's works to the state, they can get some protection.

The country's pharmaceutical business is doing very well, and the countrymen don't get sick so much, and they don't see a doctor much, but they still see a doctor when they are sick.

In particular, the poems and books of the two doctors of the Su family are really very good, so everyone trusts them very much, and trusts them even more in the medicines they produce.

After being bombarded with frostbite ointment, cold medicine and fever reducers in winter, insect medicine has become their first choice in spring.

In addition to the insecticide medicine in spring, cold medicine and fever medicine have also been sold, after all, in the spring, because the snow is almost melting, you will still get sick.

Su Lan has researched medicines to remove skin itching, in addition to skin ointment, Su Lan also made rheumatism cream, because seeing that the snow has melted recently, the weather will become cold and wet, so people with rheumatism will get sick.

Rheumatism medicine really becomes ointment, rheumatic ointment is applied to the rheumatic pain area, and the ointment will be much more comfortable after the effect of the ointment.

and Su Lan has researched drugs that can cure asthma. The Great Northeast has not yet grown poplars and willow flowers, but the local growth in the south now has these flowers, and when the time comes, the tidbits will be all over the sky, and patients with asthma will be unlucky.

It's just that Su Lan didn't hand over the asthma medicine, and she still needs to make money.

She provided some medicine that was good for the soldiers to the military, and that was because she needed to seek the protection of the military.

And there are some pharmacies that she plans to use to make money to support her family in the future, and of course it is impossible to give everything to the military.

After all, Su Lan is the one who provided the prescription, and the Su family has also gained some benefits from the medicines made by the military, so why is Su Lan embarrassed to get some money from the pharmacy so hard?

At the end of February and the beginning of March of the lunar calendar, Chen Zhanguo's twin sons were born.

The third day of the third lunar month is the time when Chen Zhanguo's twin sons were born.

The twins in Qiu Lingyu's belly have been more than seven months, and they will be eight months in a short time.

But on the third day of the third month of March, the child in Qiu Lingyu's belly couldn't wait to come out.

On this day, Chen Zhanguo, as before, cooked for his daughter-in-law who couldn't see his feet every day with his belly bowed so much, because Su Jimin and they all told Chen Zhanguo that twins were easy to be born prematurely, so when his daughter-in-law's belly was too big, Chen Zhanguo didn't go out much, so he stayed with his daughter-in-law all the time.

Fortunately, spring ploughing has not started yet, so Chen Zhanguo still has free time to accompany his daughter-in-law.

Chen Zhan Guo had nothing else to do during this time except for occasionally going up the mountain to see if he could catch the prey and come back to make up for his daughter-in-law.
