Implementation of Items

Hello, I'm pretty new to Unity and just playing around with some stuff and now came to a point where I don't know if the solution I came up with really is a good way to do it.

I want to put items into the game. Static items with fixed attributes. Startin with a Heal Potion, I tried to make it really easy to create new items. My idea was to make a bunch of effects, than create the item and give them these effects with some concrete values. Therefor I create some classes in C#, like "potion" and then create a GameObject for each Potion I want and put the script on it, then give them the objects linked with the effects and some values.

Here is a simple example:

 public class Effect : MonoBehaviour {
     private  List<GameObject> _target;
     
     public Effect() {
         _target = null;
     }
     
     public Effect(GameObject target) {
         _target = new List<GameObject>();
         _target.Add(target);
     }
     
     public List<GameObject> TargetList {
         get { return _target; }
     }
 }

 public class Heal : Effect {
     public int _healing;
     
     public void ApplyEffect(int amount) {
         List<GameObject> targetList = this.TargetList;
         
         foreach(GameObject target in targetList) {
             if( target.GetComponent("playerStats") != null) {
                 target.GetComponent("playerStats").GiveLife(_healing)
             }
         }
     }
 }

 public class Item : MonoBehaviour {
     public int _id;

     public int ItemID {
         get { return _id; }
         set { _id = value; }
     }
 }

 public class ItemPotion : Item {
     public GameObject[] effects;
     public int[] _values;
     
     public void Use() {
         for(int i = 0; i < effects.Length(); i++) {
             effects[i].GetComponent(effects[i].name).ApplyEffect();
         }
     }
 }

Now I have 2 GameObjects, an effect and a potion. Would be easy to create another potion, with more healing maybe. But i think its a very complicated way to do this. Is there a more common way to do this?
